Let's take our time on towers and keep clipped in at ALL times. This WILL avoid tragedies. Gee, I just noticed that I am fast approaching 40 yrs of age, and am no longer that "superhuman" 20-somethin
Hi Paul, Boy, this does sound like a great place to mount a HF vertical. Bonding each of the metal roofing sheets together with a short wire strap wouldn't hurt anything, and seems prudent. I'd recom
Hello, In the early nineties, I installed a fairly equilateral, 75 meter delta loop utilizing the paralleled and taped coaxial feedlines described. The loop was fed with 2 each RG-62 lines (93 ohm co
Correction... I meant to say we used a four-to-one (4:1) balun, not the 1:1 typo mentioned in the first paragraph below. It transformed the 150 to 200 ohm antenna and coaxial balanced line impedance
Hi Mark, Do a search on the internet (Google) for what is called a UFER Ground. There are many hits on this type of cement foundation grounding method. I hope this helps... Besides following the NEC,

Hi Bill, As another ham mentioned, I have also pulled up a 100 ft of Rohn 65G at one time, but in the middle of the Alaskan arctic winter of 1998. This was done at a new ARCO Alaska oil field called
3 S-unit advantage??? Not based on my 7 years of operation there... Negative S-unit(s) maybe... I'll have to agree with Mark concerning his operating comments in Alaska. After living in the Anchorage
Hi John, I wouldn't use LMR 400 (or other large diameter LMR series cables) for any situation where the cable will be flexed. Consider LMR 400 a poor man's hardline, and treat it as such. This means
Hi Bill, I would follow Mr. Katz's advice. Follow the Mfgr's suggestions on digging a proper hole and building a new base for the crankup. This is the safe and prudent approach. IMHO, using the old b
Yep... it's hard to beat these simplistic center-fed antennas that Tom has described. Just match or "tune" these low loss antenna systems (system = antenna and balanced feed line) with a capable tune
Hi Joe, Thanks for the additional info on the G5RV. It's nice to converse with you on the subject. As a matter of fact, I've never tried a G5RV after seeing one while pulling it up at a friend's hous
Hi, Scotch 70 also works quite well. It's a self-fusing, high temperature, silicone rubber electrical tape composed of self- fusing, inorganic silicone rubber that provides a waterproof seal. I also
Hi Jim, Here are a couple of obvious suggestions, but some other helpful ones (I hope). 1. Use the proper size cad-weld form for the wire ground rod sizes you have. 2. Make sure your rod and copper c
Guys, Curt, but interesting comments... I attended Dayton in 1999, and found I was one of the few "younger" men there. I was 33 years old at the time. I also finding it VERY difficult to converse wit
Hi, I'll agree with Tom on this one, too. UHF connector and adapter losses at HF frequencies are negligible. Please see the towertalk thread on this subject from just a few months ago. In this excell
Jim and Kelly, Interesting thread... While the in the USAF several years ago (less than 10 yrs), I made ground point resistance/impedance measurements using a bridge device like you've mentioned. The
Harger's site and catalog also contain some useful info on grounding and bonding. URL: www.harger.com Hi, Mark; Good information is available in PolyPhaser's book and in the application notes from IC
Since your Hustler vertical is above ground and roof mounted, I would install at least one individually cut and tuned 1/4 wavelength radial for each band of operation. Four or more would be better. T
