Just few years back (wasn't all that long ago) when we had the world wide openings on 6-meters I head a station call CQ several times but didn't get an answer. His signal wasn't all that strong but i

My system pretty much destroyed a TB-3 in about 5 years, but I over worked it to death. I agree with Bill, the TB-3 should be fine for your use. I think even the lightly built Yaesu thrust bearing w

That's either a very expensive college or cheap tower installation. A good size tower that requires engineering at the local level (in some areas) could send a kid all the way through some four year

Ahhhh... We were discussing the guy anchors not the tower base. Tower base, I agree, Mine is about 6" above grade and crowned to keep water from collecting. Up here a tower base would fail long befor

According to the Hy-Gain site the Dis72 is a 7 Mhz antenna with two elements using a hairpin matching system. Hence the 72. They don't give the weight, but the turning radius is 25' and the Effectiv

Here's not too bad. Just point it where the compass says and then add about 6 degrees. The antenna will never know if you are off a few degrees any way unless working EME with a very large array or d
