Mine tunes between 1.1-2swr 80-10m no problem Don’t blame bushcom when the antenna is second hand & an unknown quantity I’ve even made a homebrew copy and it works fine as well. It’s a good antenna for NVIS Yes it can be directional. It depends on the Earth of the ground that you steak is in as well and the signal could be lower than a dipole depending how close to the resonant length of the Antenne as it’s loaded like a beverage antenna with resistor in the driven element but even if the radiation is a little bit less and the signal is a little bit lower you don’t need a tuna for the whole HF band other than maybe 160 m and it’s a very low noise antenna being DC grounded doesn’t pick up much static they are very good temporary antenna and I have one permanently up at home as well as a terminated to wire folded dipole and I don’t need a tuna for that either

Great idea BUT if I wanted to copy what are the specific part numbers used and manufacturers ?

Who would have guessed that the orginal digital mode en.wikipedia.org/wiki/List_of_amateur_radio_modes#:~:text=Radio%20telegraphy%2C%20designed%20for%20machine,the%20first%20digital%20data%20mode. would still be going strong more then 140 years on. Wonderful effort by the Redcliffe and Districts Radio Club in the annual Harry angel contest.

What is your portable radio you have there? It looks like am Icom IC-7200.

Thanks for this video, I’m a newbie and am looking forward to trying it out! Thanks from Gary vk3gaz

fantastic team work

nice to see you again John congratulations great job 73 from kb2uew

Thank you for explaining this, I've had 20yrs out and have just come back into the hobby and this explanation was really hard to find somehow, one of those things I was embarrassed to ask 73's M1BZH

Hi John, what wire are you using and where do you source it in Queensland?

What’s a quiz pole? Is it available State side? Thanks fer da nice video!!

Nice

Love it. Is it same day every year?

Link to the springs?

Just a little correction. As the tree grows the antenna height will remain the same. Tree growth comes from the tips. The tree will get wider where the antenna is placed but not higher.

Which antenna gave the closest contacts.

I know this video is old, but I'm pretty certain the previous owner has screwed up the unun on yours. I've made a homebrew fairly close copy of the Mil-1, with home brew 9:1 unun at feedpoint and a 470 Ohm this film carbon load resistor. Dimensions are as per the Mil-1 spec. And I don't need any tuner at all across the range 160-6m. Performance is pretty decent too, even in my typical set ups running it horizontally at head height hooked up in gorse bushes. Working UK to US and South America and right across UK and Europe, on multiple bands, with just 5W CW isn't too shabby! 73 de M3KXZ 73 de

Hey John. I know it is a few years since this clip but, I built one and it works a treat! I elevated the three radials and 1:1 Balun about a metre or so off the ground and the SWR is flat through the centre and max 1.2:1 on the edges. I use a Nano VNA to adjust the height of the radials once I set up and it tunes so easy, squid pole is 10 metres long and I drop it into a pvc conduit supported by two star pickets and u bolts. I drilled a hole and put a bolt through the conduit about 3/4's the way up to elevate the pole. It was all ad hoc and works great for me. I am gonna try other frequencies and see how she goes. Cheers mate!!

Are you guys planing anymore of these? I would like to come along one day

I have the MIL-2.. It actually works really well and was recently used in the John Moyle.

Make that loop horizontal and you will see a phenomenal improvement! I built a full wave loop for 80m and it runs all the way around the forest. It is horizontal, so all the wire is at the same height. It works amazingly well on all bands. Your loop will be resonant on all harmonics. However, if you use balanced line instead of coax, that means you can use a balanced line tuner to get on all bands with little to no loss on the balanced line due to SWR. All loops have more gain than a dipole at the same height. However, if you make it horizontal, you can have some incredible gain towards the horizon on the higher harmonics of the loop. You can also improve the gain by adding corners to the loop. An infinite number of corners theoretically makes it a circle and circles have the maximum gain you can get from any loop.

Great video John! Super to see that well done comparison. Thanks!! ⚡️📻

The video sound is pretty good, beyond my imagination

Horrible audio

I’ll try it. If it works with Texas weather as well as it works down under - you’ve got something!

That's not portable, mobile maybe...

John! Please Don't forget midpoint DC EARTH on the loopantenna - this to avoid high voltage surges - which would destroy Your RXTX! Always make an earth-connection with the loop-antenna terminals *BEFORE* connecting it to any or EITHER of Your radiogear! Extreme CAUTION with loop-antenna terminals is *advised* since static elektricity buildup in the loop-antenna could "fry" every radiogear and render it useless! *A static electricity chock* is possible and could be dangerouse! *Be aware!* 73s de Gunnar sm6oer

Thanks for the video mate. I was there last week to enjoy the birdlife and it did not disappoint.

What has been your experience in comparing the dipole and full wave loop in terms of receive? Is the loop more or less susceptible to noise? Thanks, for the video! 73 AI4IJ

Very cool video! I am using a SM-5 Desk Mic myself with the IC-7300 on base station operating. I want to built me a 1 EL-Quad for 40-10m to run this portable with my Spiderbeam Fiberglas Mast and the matching Spreader Kit. and a home made EFHW vertical as switching comparisson. May be I get lucky to meet you on air to give me a receiving report. 73's de Uncle Guenter

Thanks for getting straight to the subject matter and a big thank you for your editing.

Good old dipole design always reliable , the loop being vertical as probably got a lower angle of radiation so difficult to compare but good to have the two up to try out, plus are they orientated the same way I wonder ?

Any thoughts on incorporating and loading the metal guy wire as a vertical on 40 meters??

Yet another ham proves there is no best antenna. All antennas have good points and less than good points. Weather, propagation, sun activity, soil in the area and just dumb luck all play a part.

hi my friend john 73 kb2uew

No problem on the return remarks John! watched the video again while I was here. And Enjoyed it as much as the first time. One always seems to come away with a little bit more each time!. Tnx agn fer sharing. 73 gud CUDTL? de WA1RKS

Hi John, how did you have it polarised? if you had it vertically polarised, then you are comparing vertical with horizontal. were they both in the same plane? how did the loop perform on 20M?

Who cares what the match is, if you are in the A-hole of nowhere in Auz and you can work some ham on Svalbard Island, it would seem the antenna is working FB.

just found this video John nicely done, Thank you!. my only question is was the loop vertically polarized? or Horiz. I know it was physically vertical. but where was the feed . My understanding is on a loop it depends where the feed is for polarization? Obviously that would make a huge difference against a Horizontal dipole? Thanks again for taking the time to do all of worked and comparison, and better yet for sharing it with us. 73 Gud dx de Ellis/WA1RKS

Thats what bullbars are made for

I like your garage.. what brand are the cabinets mate?

Thanks for posting this, it's been a useful comparison based on real experience.

Hello John: Thanks for the great video! My greatest problem is getting a power cable threw the firewall. Could you do another video on this. 8P6RC

That's for your time and advice.

I have a question as I have yet to engage in long wire antennas. A 10 meter wave length is roughly 33 feet (32.8) and it should be resonant as a 1/2 wave antenna for 20 meters and 1/4 wave at 40 meters (unless there is something I am missing.) Is there a problem working that backwards? I mean using a wire say 40 meters long as a 2 wave 20 meter or 4 wave 40 meter antenna? My query: *If I build a 40 meter full wave antenna will it be resonate as a 2 wave at 20 meters and 4 wave at 10 meters?* In have never seen this demonstrated and in the books I have read on wave propagation, in have never seen it discussed. I stumbled across (FIA) frequency independent antennas but have yet to see their tx abilities as compared to a dipole. This FIA intrigues me and it will be my next objective to build after building this multiple band long wire antenna. Now, I have experimented in many types of antennas over decades. I usually have success but success that has been limited to but always with limitations. I also have held the notion that the antenna should be built differently than current and yesteryear technologies. (Although there is something simular in design that works but is also found wanting.) Thanks for your help 73' s. My old call sign was N8YPS. I will retake tests soon and try to regain my old call sign. If you would like something original to experiment with... (It may be a dumb idea, but...) Try using guitar tuners on a wire antenna to stretch it's tune, while fixed at a given frequency, see if it changes anything. I haven't tried that yet but I do plan on it and will start in 2 meters I think.

Well done John brilliant thank you SeanZS5X

I hope you got that discount mate!

Good conclusions from your observations at the end. A suggestion - some of your partners were receiving you 15 db over S9, for example. At that level the S meter is in a very non-linear portion of it's range, so small changes are most likely overcome by QSB. Even if propagation was rock solid it is unrealistic to expect a station to be able to discern a difference of even a few db at best. A more meaningful test might be to lower your power so that you are closer to the noise level at his receiver. Then he will tell you if one antenna made you more readable. Because that's the reason you are doing this, right? (to be heard when conditions are tough?). To do that may be difficult as even dropping from 100 watts to 1 watt is only 20 db and you were usually in the range of 20 over 9 to them anyway ! Thanks.

Excellent John, i planning a horizontal 80M full wave delta loop, at 30ft each leg..

we need to do a big shot instructional vid

interesting John, I made quad antennas for 27mhz years ago and found they out performed a vertical 5/8 ringo mounted 20ft above it. and the comparison against the dipole which most use as a base line for gain etc, was interesting as well. i have to say i did not hear you on the moyle, but i was not hunting , i sat on 1 freq and called.
