Hello all,I am about to construct a 12 turn on 2.4 od #31 choke from the cookbook using the described #14 THHN. I have come across references to the possibility of voltage arcing through the insulat

Do it like the pros. Rod chairs (sometimes go by other names) made of plastic or metal, allow the bar to sit above the ground. Cost is minimal. They can be obtained from your concrete supplier or fro

Use doby blocks. You do not want to use regular bricks. They will absorb moisture, again causing the rebar to rust. I did that on one of my first tower installations, and the inspector would not pass

forward in building the cage and pouring the concrete. I have read the the rebar cannot be with in 3" of the dirt or it will rust and fall apart. What do you do in the bottom where the rebar sits on

Yep...here it is. When using a roof mount you are forced to keep the tower guyed at all times. For modest installations, 50 or 60 feet it is a cinch to haul a Yagi up the side of an unguyed tower. Af

Jim, I suggested that but Larry sez he can't do that. For others, my 80m cage inverted vee (sans feedpoint choke) functions on 160m as a vertical w/ top-hat on 160m. The apex is at 70' AGL w/ about 8

Jim, Wasn't the gamma match intentionally designed to have the shield of the coax directly connected to "ground' (boom that is)? Worked for me. Hans - N2JFS Really? What's to stop CM still flowing al

I like to use the doby blocks that come with a hole half way through. This allows the rebar to set inside and I find it works better than the ones with the tie wire attached. If you can't find them,

Another way to add 160 to the Hytower is use one of the mobile antenna coils from Hi-Q or similar. You then have a remotely tunable antenna for 160 and 80, with out having to change taps. Skip, KJ6Y

For 160-m. I agree with John's statement below, unless the vertical is real short and base loaded in which case I'd prefer a low Dipole or Inverted Vee on if there's no better option such as a top lo

I think we are using "Cheapskate" the wrong way. Most every ham I know wants to get the most "bang-for-the-buck". That doesn't necessary makes us into "Cheapskates". To me, a "Cheapskate" is a person
