Part 2 of my low level 80 metres horizontal loop project. In this video I get the wire for the loop into place. As I’ve said all along I'm deliberately keeping the loop low as I don’t want it to impact on the landscape. For the record at this point in the project the loop runs from the start point 39 foot to the east then 69 foot to the north then 21 foot to the west and finally 112 foot to the south to give an overall loop length of 241 foot. When I made this video I had it in mind that I needed to make the loop larger but I suspect that because of the low level of the loop that a length of 241 will be somewhere near resonance for where I want to be on the 80- metres band.
At the recommended height of 40 foot above ground a 80 metres Sky Wire should be around 272 feet long but in my first trial with the wire lying on the bushes I found that resonance and the best SWR was achieved with a total length of just 235 foot.
The coordinates are reasonably in line with true compass headings and I'll be feeding it in the south-west corner. (I guess I could easily arrange to feed either the south west or south east corner without too much trouble.)
If editing and uploading was easier I’d no doubt have covered the project in one video but as it is I find the convenience of just shooting and uploading from the phone/camera too good to pass up but it dose mean that you get all of my fumblings and repetitions along with what is hopefully the more interesting content.

Thaknks for watching.

Hi Andy, I just installed an 80M Skyloop using 14awg coated copper wire, 280 feet in length, at 45 feet higher in a rather square pattern. Corner fed with LMR400 coax to a 4:1 Balun made by Palomar Engineering... model CB-4-1-1500. Fairly resonant with 2.5 SWR at 75M, 2.1 SWR at 40M, 1.5 SWR at 20M, 1.8 SWR at 17M, 1.1 SWR at 15M, 1.3 SWR at 12M and 1.4 SWR at 10M. Works well, is quiet and so far signal reports and DX are great at 20M and higher. I started at 280 feet in length so I could trim it down if needed but so far it is transmitting and receiving really well. Cheers, 73 Art W1SWL
Great video Andy, and yes your All Creatures Great and Small reference definitely rings true for me :). One easy question, how tall is that aluminum mast you have up?
Hi Neil
the mast is around 31ft (~10 metres)
Regards . . . Andy
GREAT to hear from you again!
How are you not seen anything new in a while. UK CB radio user.
It's been a while, hows the dx going with this antenna?
Are you still working on the HHO?
Since I have been watching you talk about the antenna and stuff, I got an idea. This is not about the subject matter you are talking about so please forgive me for going off topic. Hope that is all right with you Sir?? Would using a controlled induction heater be used for heating a home in the winter ??? My reasoning is that since the induction heater is a very efficient way of using electricity, this somehow would work with the proper design. What is your view fella on this subject. Nice video fella too. vf
Hi although induction heating is a very efficient form of heating for a lot of industrial and scientific applications (and cooking) it does have some inefficiencies.
If you have to use electricity to heat your house, you’d be better off using a resistive element. It would be much cheaper to purchase a resistive element and it’s housing rather than an induction heater with hundreds or even thousands of components which are expensive and with lots of joints all of which could potentially fail.
I don’t respond to many comments these days but I just happened to see yours today.
All the very best and kind regards . . . .Andy
@@AndyDaviesByTheSea I want to thank you Andy for setting me straight when it comes to induction heating for home heating. My thinking for some reason was a bit off. So nice for you to set me straight for future thinking.
I would like to experiment with induction heating but getting the correct capacitors is an expensive endeavor. I hope that somehow some can be had for a decent price to experiment with the art and can send you results for guidance and oversight.
Good day to you Andy and enjoy life down the shore. I know from experience that looking out to sea really puts one's mind at ease. Peace, Victory First
@@victoryfirst2878 At least here in Australia, without ..any doubt, ..the, ..most ..efficient, way to use electricity, to heat your house, is via the use of a Reverse-Cycle Air-Conditioner..! Basically it is just a ‘Heat-Pump’ which robs ‘free’ heat from the external environment and ‘pumps’ it into your residence, when running in ‘reverse-cycle’ mode, but, I don’t know how well that would work in England, at least, during your ‘snowy’ Winters with a force-10 arctic gale blowing in from the North Atlantic..! 😉🙄
@@wa7215 I understand the idea W A. Different place different ways.
@@victoryfirst2878 If you really, like the idea, of using ‘induction heating’ to ‘warm your house’ V.F. why not save yourself a whole lot of additional, and unnecessary extra expense, and just use, it, to ‘warm’ only, yourself. 😉 All you would then, need to do, is simply find yourself a ‘Microwave Oven’ large enough, for, you, to hop inside of it, before hitting the ‘GO button’. 😉 I am, joking, of course. 😉😉
Nice to see you again Andy, dont hear much from you these days. What's your call sign? I will see if I can recieve your broadcast in the SW.
Hi the call sign is GW0JXM
(That's Golf Whisky Zero Juliet X-ray Mike but when I'm calling DX I always call 'Golf Whisky Zero Japan X-ray Mexico' and somehow the 'Japan X-ray Mexico' gets a better response than the Juliet X-ray Mike) I can't tell you when I'll be on the air as I'm not a creature of habit.
All the best . . . Andy
"But of course I forgot to slide them onto the wire first of all" - That has got to be the all-time classic with anything involving wires :) Be it plug housings or heatshrink, or in this case insulators. That place looks very lovely, I don't know anything about antennas or probably most of the other of your videos, but still enjoy them! Thanks
Hi Andy, give shotcut a try. It's free open source. It's not quite as straight forward as adobe, but it's free and it works
Andy sir can you help me I am your Indian subscriber
