- This video lasted a bit longer than was intended,🙃 but it gives you a very good idea what to expect if it's by the serial which myself think could be very well used if it was a little bit higher and possibly a bit more out of the way of the roof, but you can see it works on many many frequencies and some operators and hear me very well, which is very surprising🤔 as I say again because the aerial is far from an ideal position. It's very well made and even the radials seem a very high quality, and also the brackets. At this moment I am quite pleased with the aerial. I'm not really surprised on 160 and 80 meters it doesn't work so good, but I'm sure when the aerial in a better position if we also work better,I hope that someone finds this video useful,,,73s from Rotterdam,Deze video duurde iets langer dan de bedoeling was, maar het geeft je een heel goed idee wat je kunt verwachten als het door de serie is waarvan ik denk dat het heel goed zou kunnen worden gebruikt als het een beetje hoger was en mogelijk een beetje meer uit de manier van het dak, maar je kunt zien dat het op veel frequenties en sommige operators werkt en me heel goed horen, wat zeer verrassend is, zoals ik nogmaals zeg, omdat de antenne verre van een ideale positie is. Het is zeer goed gemaakt en zelfs de radialen lijken van zeer hoge kwaliteit, en ook de beugels. Op dit moment ben ik best tevreden over de antenne. Ik ben niet echt verbaasd dat het op 160 en 80 meter niet zo goed werkt, maar ik weet zeker dat als de antenne in een betere positie staat als we ook beter werken, ik hoop dat iemand deze video nuttig vindt,,,73s van Rotterdam,👍FEATURES, FUNCTIONS AND SPECIFICATIONS:

My Best DX, ZL4AS from UK with 2.5W, FT8 on 17M
QRP is a passion, long hours of dedication.
Got this antenna about a month and a half now placed on a satelite foot on my balcony.
I don't even have to raise it up and I'm allready making contacts 3000km away easy even with 50watts or less.
It's defintely a kind of DX antenna because everything in a radius of 500km is almost not workable. Further away no problem at all. I got 59 reports 3000km away.
Hi,good for you, it seems money well spent, 73 from Rotterdam
Very useful thanks! I'm going to try and put in a 20m long wire instead!
Hi,yes good decision, and you save some money 💰,,,73s from Rotterdam.
Great video very informative
I have the SE Hf X-80 1KW Vertical and I will add the plus kit to it see what it’s like 👍 73
Hi,good choice 👌, try to fix it as high as you can, what does it cost with the radials. 73s
@@Bernard-John It’s was £140 for the Aerial and £72 posted for the radials
@@freedom_unite3845 thats not so expensive, relatively speaking,,,,give me a shout out on 40 meter, I am curious of the performance,,73s
@@Bernard-John I will do no problem just setting up about do my foundation and joined the RSGB then i'll be up and running ( just listening at the moment ) , i did all this in the 80's and 90's just decided to take it back up but legally and all above board 73's
Also we have just had two storms in the UK and the sigma stood up to the 100 mph winds very well
Hi,I found the Sigma to be very good quality, good materials used 👌, I have sold mine and in the middle of replacing it with a 40 meter end fed wire,,,,well that's the plan,,,,73
@@Bernard-John you will notice the difference on receive for sure.
@Captcasper7 Hi,I hope to use a tree in park to hang the other end,40 metres is a long long wire,,,73 from Rotterdam 👍
very good, did you connect the base pole or mast to ground?
Hi,unfortunately it's not possible to earth the antenna, 73s from Rotterdam 🙏
Does this antenna work better with the radials pointing down or up. I have mine pointing up at 45 angle
Up, they are basically resonators.
Hello, thanks for the video. Can you tell me how much difference the Plus kit make. I have SE X-80 and did contacts up to 10000 km with the IC7300, no amplifier on 10 and 15 but the 40 m is so-so. How much range extension did you get with the radials compared to the bare X360? Thanks and 73
Good morning 🙏, I found the antenna is for compromised situations, example a radio room with little space for a a antenna, I didn't find any difference with or without any radials, maybe for you it's different, good luck 😉, 73s from Rotterdam 🙏🙏
How did you fix the 1, 35 metre steel whip at the top? How deep inside? There is no mention in the manual of what to do...maybe for SWR adjustment how?
Great video, thank you! But you have an extremely high background noise with S7 to 9, is that normal?
Thanks for this - I'm still thinking about buying the radials. Do they make a difference?
Hi,to be honest, the sigma HF 360 was not in the best position,,,so I can't give you an honest answer, but unfortunately for the Bands I want, 80 meters and 160 meters I am going to try a 40 meter end fed wire aerial sometime soon,,,good luck ,and 73 from Rotterdam 👍
it would have been nice to see what your swr was before and after i have sigma and i have a problem getting my swr down below 3.0
Hi,my SWR was also round 3,but no problem use the antenna tuner,,,,that's what it's there for,,,,try extending the radials,,,,and open standing seems the best,,good luck, 73 from Rotterdam 👍
Well I haven using the Sigma. HF360 with radials upgrade for over two months now and it does ok, but I have just put up an end fed multi band wire antenna (length 20m of wire with a transformer) and it receives and transmits much better than the Sigma.
Hi,I know what you mean, but the Sigma HF 360 is for operators with limited space, I agree a 20 meter wire will work better, if you have the room for it, good luck 👍🏻 73 from Rotterdam.
@@Bernard-John I had to manipulate the wire around the garden in sort of a three sides of a square
Is it a UK antenna?
Hey you are Mister Jean , Yeaaj John from Charlois Yeeaaass I hear it , Yoy Mrs John , the Engelischman , with a new bakkie A Icom IC 7300 From Rotterdam by Southplein , 😂😂😂😂
Yes guilty as charged,,,but with a ICOM IC 7610 and Acom 1500 amp 😬 73 from Rotterdam.
I bougth a Sigma 360 and the Balun melted using FT8 at 80 watts. Three months of use and it had to go in the bin. Never had a voice CQ on it.
Hi,well that's a bit unlucky,,,I suppose you could have replaced and upgraded the 9 to 1 Balun,they are as cheap as chips 🍟 😉, I just used radio power 100 watt's max on fm, hopefully the next antenna will be better, thanks from Rotterdam 👍🏻
@@Bernard-John I just don't know why this issue happened after 3 months. I will "upgrade" the antenna to another make. Antenna is glued together.
@ultraforce351 Hi,is it not possible for use a wire aerial, maybe it will perform better, 🤔 and definitely cheaper,,,good luck 😉
@@Bernard-John Unfortunately I am in a city type area. I can not do a wire but will try a better vertical.
@ultraforce351 Hi,yes it's difficult to place big antenna on roofs, but a 10 meter wire should not be so difficult to put up, don't give up, 😉 you will get there in the end,,,73 from Rotterdam
Couple of months later ... propagation been good last weeks. Can you give us an update how the antenna is doing these days ?
I got a telescopic aluminium pole sitting on my balcony about 2m30 from the ground. I could get the foot of the antenna raised up 8 to 9m above the ground level. Since it's on a balcony ... I really don't have an other option then going vertical ...

Hi,unfortunately I have sold the Ariel few months ago, I was a bit disappointed with the performance, but mainly it has a 400 watt maximum imput, I was afraid of damage, so I ordered a 4 element 6 band's yagi which should be here in a few days, finally, but the sigma hf-360 is for operators with limited space, and HIGHT IS MIGHT, higher the better, good luck 👍, 73 from Rotterdam.
@@Bernard-John i live in the Netherlands also and getting my licence hopefully at the next exam.
The radio I made my choice the 991a from yaesu but the antenna I can't make a choice maybe you can help me a bit.
Can you give me some advice looking for a dipole for all HF bands and an other antenna for the 2 meter band thank you very much
@@DO1BTW Hi,it's difficult to give you a opinion without knowing where you are going to place your aerial, there's so many influences, example, how much you want to spend, where its going to go,maximum power output ,but I am sure that you will figure it out, good luck with the exam, 73 from Rotterdam 👍
My next HF antenna
Hi,good for you, try to put it as high as possible, away from structures, let me know how it goes, 73 from Rotterdam 👍
have you got the length of them please I cant justifiy spending nearly an extra £100 just for some radials. If I can get hold of the lengths I can make some wire ones.
Are they not just AM PRO-80 and AM PRO-40 made by the same company. You can buy both of those for about £19 each then make a mount. total cost about £25 as aposed to nearly £100 for the kit
Hi, the radials are loaded and are swr adjustable,,,difficult to measure,,,but download the spec from Sigma,,,thanks from Rotterdam
@@Bernard-John many thanks and 73 de 2E0LIG
hello could you give me more information about this antenna. I would like to use it on the 27 MHz. I wanted to know if it is necessary to use a tuning box on this frequency? thank you
Hi,for the 27 mhz I have my Gainmaster 5/8 wave, the Sigma Hf-360 was mainly tested the amateur bands , sorry can't really help, but good luck 👍
de 80 meter wil niet echt vlotten , jammer dat je niet meer laat zien op die 80 meter , een antenne die 1-1 loopt da's mooi , maar geen rendament op 80 meter . jammer
hallo, ik vond het niet zo goed op 80 meter, maar misschien als de vermeerdering in de zomer aantrekt, zul je merken dat het veel beter werkt, maar goed nieuws voor de swr, misschien spreek je snel, bedankt uit Rotterdam 👍groetjes bernard,
There not racials they are tuned antennas for 40m and 80m to improve those bands
Thanks for your reply 👍, I my situation they didn't make much difference, but the aerial wasn't in an optimal location, thanks from Rotterdam 73
@@Bernard-John agree I've got one but not fitted the add-ons it works but not a patch on my long wire. If you can get it off the ground by s couple of meters it will work better
@@billbones9635 Hi,I agree, but the sigma HF vertical is for operators who don't have the space for a wire,thanks 73👍👍
@@Bernard-John Too true, it would be nice to have the space
So radials pointed up or down for best results
Hi,to be honest the Sigma HF 360 was certainly not in an ideal position, I am informed that if the radials are pointing down, it reduces qrm and other issues,,but I can't say for sure, give it a try and let me know,,,73 from Rotterdam 👍
After using this antenna for a few weeks now, I find it receives better than it transmits at present. 20 meters is the better of the bands, but my antenna matches struggles with 20 meters yet does really well on 40 meters.
@@Captcasper7 Hi,actually I found 20 meter and 18 and 15 and cb frequencies and 10 meter working good, but 40 wasn't so good, but the aerial was to low down,,,,but good for you 😉,,,,,thanks from Rotterdam AND 👍
@@Bernard-John My antenna is at a height of 6 meters above ground.
@@Captcasper7 Hi,so long that it's higher than the roof, is a minimum height for all antenna to work well,,,height is might, as they say,good luck 👍.
What are your conclusions????????
Hi,well everything is a comprise, if you have little space for anything bigger, we'll it will work, just put it high enough, but don't expect miracles, I am sure a 20 meter wire will work better, good luck with that 👍 73 from Rotterdam.
I had mine for 2 years no issues with strong wind i found the add on were vast improvement . I use a tuner but not really needed as both swr are less than 1.6 on 40 and 80 . As for tx i run 10w and chat all over europe no problems and sure i can get further if i put the effort in
Hi I have the same antenna works well this end and the add-ons which at the moment point pretty much vertical as to the picture which came with the antenna what position do you find the best ? Check my video out on here
Hi,I can't say for sure, I am going to replaced it with a Sigma lw 40 end fed wire soon, good luck 👍
I have the same antenna does it matter if the add on radials are pointed down like yours or in the up position
Good morning, from what I remember, it's recommended and is practical to point the radials downwards, but at the end of the day,it's what works best for your situation,,,,,good luck with that 👍, 73s from Rotterdam.
