Dave, this has been discussed many times on this reflector and is in the archive. The easiest way is to look in your newspaper in the weather section for the sunup and sundown times. Divide the time
I am almost positive it was Harbor freight and it was some kind of sale. I believe there was a later post about getting an adaptor to fit the drill chick to the ground rod. Seems like this was only a
Steve, I cant comment on the radios but if the roof of your motorhome is not metal it would probably work OK. I have seen emergency ham control center setups using loaded mobile antennas in a horizon
I recently purchased Sevicks new book "Understanding,Building, and Using Baluns and Ununs" . It covers designs with ratios from 1 up to 16. I particularly like the fact that he talks about power rati
Hi Greg: The HF antenna question is the easiest to answer. There should be little or no coupling between the vertical 10m ant and your tribander so spacing is not a problem. I assume the vertical doe
We have used an aluminum sectional ladder to push up a 60 foot aluminum tower past the difficult area you mentioned. A rope, tied near the tower top, was used to pull it up the last part of the raisi
I am interested in an unidentified crank up tower. Can someone help in determining the manufacturer? 1. 3 sections, top section about 12 inches/side, lowest section about 17 inches/side, 18 ft long.
Dan: I have read of people using several 55 gal drums as rollers under a crankup to move it off a truck and to the install location. It seems that this would cause a minimum amount of damage to a law

Richard: The BW you describe means one thing to me, serious loss resistance in the vertical, probably in the ground system. Re the Greenlee punch, I usually unscrew the bolt several turns then tap th
Hi Don: One of the locals here(K7OX) tried the 731 and it didn't give him enough attenuation in his strong BCI environment. We finally used an MFJ noise bridge with a battery powered SW receiver and
Mark: Nice beams. Are the loading coils the small bumps I see about 2/3 way out each element?.What is the material used in the center of your elements and how long is it? Are the F12 and HyGain eleme
Hi Ken: It is possible to put RF into almost any thing and make it act as a radiator. I once used the windshield opening in my car as a slot antenna on 10m. However, the setup you describe does not s
I need several dozen PL259s for a project. Looking thru the ads I find the lowest price seems to be 10 for $9 for silver teflon/gold plated pins at The RF Connection. Has anyone used these and found
Bob, it is almost a certainty that you need to tap the tower much lower. I just finished helping a friend tune his 65 ft aluminum tower for 160. He has a TH6 on top. Our first tap was too high but st
Hi Van: L.B.Cebik has done extensive modeling on quads. You can find a lot of info on his web page www.cebik.com He has also written 2 books on quads which I have. He found that multiband quads with
The 2 UST crankups I have are not tapered and the looseness between sections is needed so they don't jam up, particularly when you try to lower it and a side wind is present. My 472 does not have a w
