I've been using a 10 amp 240v AC cheapy relay for my 100 watt station without problems for eight months. I ran three 450 ohm ladder lines in from three directions at right angles and the coil voltage

I just did this with a vice and channel locks. Put the first thimble on its turnbuckle in about 30 seconds with no damage to the galvanizing. I feel dumb but happy. Thanks guys! -Pete KS4XG -- FAQ o

This subject was debated on Usenet and the guy who designed the coax coil baluns described in the ARRL Antenna book responded to the "oatmeal box" flat coil proposals, explaining that he used a serio

Hi Folks, While putting up the first part of my tower I stripped the threads on one EHS cable clamp (clip) and broke another one. This was with a ratchet wrench with a 6" long handle. I'm no strongma

I got no numbers or anything objective back from your collective wisdom in response to my questions about cable clamps and "how tight is tight." I broke another one two nights ago so the tally is now

After seeing a reference in Dave Leeson's book I dropped by my local REI store and found some nice mountaineering pulleys. The two I got are going to make light work out of some lifting for my tower

Hello Johan, I'm copying the reflector in case we both might get some insights about the quad antenna type based on two wavelength long elements. By coincidence lately I've been time modeling bisquar

(by direct mail you said it's 2 wavelengths on 40 meters) This isn't a bisquare. The current distribution is very different from that of a bisquare and in fact it has a large proportion of vertically

Hi, Anybody out there have a clever trick for getting an antenna description based on an EZNEC model into an ASCII file? Maybe some DOS incantations that will cause the PD command to go to a file ins

The Texas Towers joint bolts are plated, not galvanized. But what really slayed me was getting plated U bolts on the "Rohn accessory shelf" I bought from them. How is that possible? Regards, Pete KS4

And sometimes the truth isn't so obvious. I'm told that the reason I got plated bolts and nuts from Texas Towers is that this is what Rohn sells and specifies for joining tower sections now. They use
