Just pack the dirt up around the bottom. It'll do fine whether clay or sand. I've gone through 30 some just packing the dirt in the trench up under the ceramic and against the rubber seal. Roger Hal

Theoretically 15 degrees wide. I think you will be able to find some times zones that are over 20 degrees at their widest points. The Eastern time zone in the US is a good example. It runs from *abo

Taking into consideration I have no antennas or arrays with a very narrow beam width I used the "I think it's about that-a-way" method for finding North. For astronomy (Telescope set up) I rough set

That's why I use a ratchet and deep well socket. I find the bolts sticking out on a ROHN 45G to be hazardous, so all of mine have the nuts on the inside. As my tower is climbed often and the torque

Usually those things slip for a reason which prevents you from having to purchase a new rotator. OTOH sometimes they slip just due to a poor mast clamp. Still it's not a good idea to pin the mast to

I didn't catch the part about it being the antenna. If so, depending on the mast I'd not be afraid to pin it, but generally the good clamps have a center bolt that is sufficient, but can be replaced

Another route is 4 half wave folded dipoles fed in phase using (I think it was a 90 ohm coax harness). You can put them all on one side of the tower for reasonable gain or orient them 90 degrees apar

The earlier ones were phenolic. I have an ATB-34 out in the shop that just uses a phenolic tube about 8 or 10" long. The elements fit into it. It is drilled and tapped, 1/4-20. They use a SS round h

Don't forget physical protection. We are almost surrounded by woods and we get lots of high winds. Although the tower is a ways from any tree it's not uncommon to see branches go whizzing by when th

<snip> But the small stuff such as RG-8, LMR-400, and even 9913 probably cover about 99% of the coax in use by hams. For me anyghing over LMR-600 would be overkill up through 440. OTOH I'd sure like

It really doesn't matter if it's through a junction, around a limb, or around the trunk. As the tree grows it will encompass the line. It looks like the line cut into the tree, but it didn't. Howeve
