I saw most of that demo as well. It was a good thing to have at Hamcom! (And Hamcom was very good this year.) During #3 below (a 6' lanyard with a knot), I managed to take a picture, right after he r

We are trying to identify this (older?) HF multi-band vertical. It has at least one coil sticking out on the side. Pictures at http://www.qsl.net/n0rq/unknown.htm ... please reply if you know what it

Pi(e) is what you do after the dipole is up. Preferably apple with ice cream on top. For those that don't cut dipoles at least monthly and tend to forget the formula, this web site, http://www.geocit

Here is a coax calculator that seems to be a good tool: http://www.ocarc.ca/coax.htm Plug in the variables, and it will tell you exactly (in theory) what the loss is. - Dave N0RQ ____________________

First thing that came to my mind would be a sweep-L made out of PVC. This would allow the wire to easily slide through it, without the need for a sharp bend. Also agreed with the other comment -- may

Here in the heavy Texas clay soils, there is an easy way to put in ground rods. I'm pretty sure it has been mentioned here before, but here goes... You must have a supply of water, preferably a hose,

There is a worthwhile "coax loss calculator" that I think is worth a bookmark... see http://www.ocarc.ca/coax.htm It includes BuryFlex, the Time LMR-series, 9913, Heliax, and a number of others. Than

Or, even on a vertical with elevated radials, if there are "enough" radials, does it really matter if the feedline acts as just one more radial? On my 40m vert, there are about 20 elevated radials, a

You can find crimp connectors for LMR-600 (and -400) on ebay. Those little gems are pretty pricey retail, but the "N" versions can be had for <$6 on ebay. (Unfortunately, the PL-259 versions are a ra

Why aluminum? Lighter, yes. No rust, true. But the main reason is that in some applications, such as a modest tribander and a couple of modest VHF/UHF beams, the aluminum is more than strong enough,

Hi Dave. Thanks for the note. And I agree completely! When I bought my 12' aluminum mast (from Texas Towers), Gerald ran the numbers for me. No way do I want some mast that is on the verge of failing

For direct burial cable (rotor, coax switching), you could use sprinkler wire cable, found at any Home Depot, Lowes, etc. It comes in various # of conductors, and can be a bit cheaper than something
