alright cheers for that. i’ll make sure i keep them seperated but before i do so i’ll try and see what happens if they touch. i just wanted to make sure that doing so would not casue any harm to the device i connect it up to.

@DRIF74 Hmm, …
@DRIF74 Hmm, haven’t tried that. I guess there’d be a more serious than minor loss in reception, rather than a complete failure. Professionally made antennas have a minimum of a half inch seperation. I think a minimum of one inch is best.

i was just …
i was just wondering about what would happen if the crossovers touched each other? would there be a minor loss in reception or a complete failure?

Thanks for sharing …
Thanks for sharing the demostration of this antenna.I made one about a month ago to see if it really works. I was really impressed. I’m receiving stations 92 miles from my home and just slightly on a hill.once again thanks for the video.

At the crossovers …
At the crossovers of the phase lines (top & bottom) it seems that you simply use a section of PVC to space and slightly bend/twist the phase line at that point to ensure they won’t touch. My thinking is that if you make the connection slightly higher, i.e. a spacer, on one of the top and one of the bottom screws, it would elevate the phase line at the crossover and ensure it wouldn’t be accidentally pushed back down. (I hope I’ve made this clearer….:P)

Thank you for the …
Thank you for the vid, I did a complete PVC build as this will always be outside. I created it with a simple to disassemble 12 foot piece of 1 1/4″ pvc vs the 34″ 1×3. Just awesome for the small campers. I have a feeling that part of the reason that I receive from such distance is that I am located basically in the plains, so flat is good on days that the wind is not blowing : ) Thanks again for the video.

Wow, that’s some serious reception. I’m pleased it’s working so well for you.

I can’t quite …
I can’t quite picture what you mean, but try it if you think it’ll be an improvement. Personally, I don’t think a spacer is critical if everything is screwed together properly.

One note that I …
One note that I forgot to add is that the station that is over 70 miles is exactly 72.3 miles and has an elevation that is about 730 feet above my central Indiana location. Thought I should add this disclamer for those who know that the world is round and therefore limits the broadcast distance on clear days.

My wife recently …
My wife recently bought an older camper and was in need of something for an antenna. I looked into buying one and it seemed the best I could buy for under $100 could receive about 40 miles. I built this with stuff lying around the garage, 8 guage copper, pvc etc. Put a reflector on it (construction mesh) and WOW, grabbing stations over 70 miles away. Full HD the whole nine yards, well worth the 40 minutes to build!!
