I had two inverted V beams (a 3 element on NA and 4 element on EU) on 20m before I had rotatable antennas. They worked quite well. I don't know what the gain was but much better than a dipole. Signal
I haven't been following this thread closely, but are we only talking about going 100 feet? That is nothing for wireless. I have a very stable 5.6 mile wireless network link that supports 30 Mbps 24x
Another list member sent me this useful path design utility for the AirMax product but appears useful for other systems. https://airlink.ubnt.com/#/ Very interesting and it agrees within 1 dB of what
Getting off topic, but back in the 70s/80s, amateur publications were claiming that if you were building something that you wanted to silver plate after fabrication (eg. a VHF/UHF amplifier tank circ
I am another solo installer. Please be careful! Erecting towers and antennas solo can be very hazardous. I don't recommend it. That said... I have erected 100 foot 25G towers by hanging a weight almo
Herb's method is certainly much faster than mine. I did three sections that way before deciding it wasn't the right approach for me personally. That's when I switched to the counterweight. Paul N1BUG
I knew it was inevitable this would turn into a safety and "don't do that" discussion and almost didn't respond to the original question for that reason. But I also realized there are some who, for w
This is the method I use. With 3/16" and 1/4" EHS on my +/- 100 foot towers I have never found it necessary to use a screwdriver or wrench to tighten the rope. Even when using turnbuckles as short at

We did the same with a 50 foot and later 100 foot repeater tower, except our trees were a little smaller and anchors just above ground level. I never like it but it was our only option at the time. H
Different animal, Dick. Keep looking, there is such a thing as the adapter you seek. I have recently seen them on eBay so you're looking in the right place. Paul On 12/31/2015 11:51 PM, Dick NY1E wro
While trying to figure out how to move up a notch from my inverted V antennas on 40 and 30 meters I came up with a crazy idea. I was looking at building a rotatable dipole for 40 meters, either full
Thanks John. I was not aware of that trap. I like the idea of requiring no band switching. The overall mechanical arrangement of the antenna would also be simpler. It appears the traps would need som
Hank, thanks for the input. I didn't like my relay idea but when I wrote that post I hadn't yet seen a workable alternative aside from full size parallel tubing dipoles for each band. I could do that
Both. I should have specified my goals. I am a DXer first, contester second. Currently I have a 40 meter inverted V, apex at 70 feet and 30 meter inverted V, apex at 80 feet. Here is what I would lik

Agreed, Mike. Looking at the picture, it will need drain holes and some sealing of the slits where the clamp is at what is intended to be the bottom end. It looks manageable, though. 73, Paul N1BUG _
I want to thank everyone who provided input on my recent question. It was an interesting discussion and revealed more than one method I had not considered or was not aware of. I got what I needed fro
