come on doc you started it now finish it. I'm just leary of anything mechanical as far as antennas go. If it burns up or get stuck what do you have????
Yes it does...or rather, certainly did compared to wire beams I've built.Hamin' X said:As MC indicated, the gap is frequency critical and this does not change much with the diameter of the antenna material.
I'd be curious to know how many you guys have made and tested with tubing over wire to where you are so confident? :shock:Hamin' X said:Also, the pattern goes kaput with frequency excursions much over 2%. You might be able to get a match with a tuner, but your signal might be warming the clouds.

I will admit that I have not built two identical Moxons, one with wire and one with tubing. Also, I have not tested them against each other, since I do not have an antenna test range to get any kind of meaningful results.231 said:I'd be curious to know how many you guys have made and tested with tubing over wire to where you are so confident? :shock:

If done at highway speeds, you get a 'L' shaped loading coil (don't ask! I'll lie! I'd never do such a thing).

Tell me about PVC being heat sensitive! But you can turn that to your advantage too (pun intended), if you don't happen to have a lathe. Position the loading coil on the PVC coil form. Apply slightly too much power and have the wire melt it's way into the coil form. Then, re-tighten the @#$ wire. Do that too long and you end up with 'curly-fries' like at 'Arby's!

rfoverlord said:well i'm pretty sure it will be a Hi-Q but maybe a high sierra? it depends how much i want to fuss with mounting/matching. and i haven't seen to many current reviews of the Hi-Qs lately. There are a few on e-ham and some of the individuals doing the reviews, I actually value their opinions based on their backrounds.
