Is a tailtwister T2X adequate to turn a DB36? The beam the guy is putting would be located just slightly below the top of the surrounding trees in a residential neighborhood so I dont expect the beam

I've had both; there's not much of a comparison. If you want a directional low noise antenna, the bev is a far better choice than the loop, even if it's relatively short. 73/jeff/ac0c www.ac0c.com al

LCP is really a PIA to inject. PTFE is a lot easier to handle and I think it's probably cheaper, plus you can grind up the scrap and reinject it meaning you get nearly 100% use of the material - wher

The fellow originally asked what coax to run. I have a comment there. RG11 is fine. If you say it's a budget consideration, and it's 80/160, and it does not need to last 100 years, then lay that RG11
