Good point. I'll look for something to wrap the end caps. Mine came with blue plastic caps. One upgrade that I did do was to get the higher power BN-4000 balun to replace the stock BN-86. ___________

AN Wireless towers don't have round cross-section legs, but rather use flat steel bent at a 60 degree angle for the legs. Most tower grounding solutions that I've seen use fittings that clamp onto a
In the case Steve is referring to, the engineer specified the "G" solid block base. They took into account the local conditions here, including my location on an escarpment, soil conditions (I provid
What is the purpose of sealing a concrete pad used for a tower base? Does this increase its useful life? There are sidewalks in town here that are probably 80-100 years old which are not sealed and I
Anyone have any problems (or know of any) with the traps on the Hy-Gain TH-7DX when running legal limit power? I haven't had any problems with SSB/CW, but want to run legal limit on RTTY and am conce
Thanks, Mike. I forgot to mention that I've already replaced the stock BN-86 balun with the BN-4000 before the antenna was installed. 73, Jerry _______________________________________________ _______
I have an Alfaspid RAK on my tower turning a TH-7DX. I cannot hear the rotator at all on the ground (the rotator is at about the 55' level on my tower). When I tested the rotator on the ground, I not

I installed a run of BuryFlex recently and was surprised at how flexible and slippery it is. I pulled it through 160' of 2" PVC conduit with about five 90-degree bends and it ran through easily with
I like 3M Scotch Temflex 2155. This is a self-fusing sealing tape similar to rescue tape, but only $2.48 for a 22 foot roll at Home Depot, and Home Depot is nearly everywhere. I wrap a connection wit

The TH-7DX is sold with a BN-86. I immediately replaced mine with the BN-4000, which handles more power. I regularly run legal limit into my TH-7DX/BN-4000 without any problems, even on RTTY. _______
Here's an excellent technical paper related to the use of silver for connector applications: http://www.te.com/documentation/whitepapers/pdf/Ag_use_connectors_503-1016.pdf Jerry, W6UV _______________
My tower seems to attract every bird in the neighborhood, and the area at the bottom of the tower is covered with bird crap. In fact, I can determine the radius of rotation of my beam precisely -- al
What is the point of a back of desk grounding bus? Does it fill any real need, or is it just one of those feel-good things that's been around forever? Surely it's not to deal with anything related to
"You are probably right, Jerry. I wouldn't put any kind of ground in. Probably just a bunch of old housewives tails from engineers who don't know anything!! You probably are right that it has no need
Hi Tower Talkers I'm planning to replace the TH-7DX on my tower with an Optibeam OB17-4, which is a much larger antenna. I'm now looking at my options with regard to rotators beefy enough to handle t
