Minimum gauge for groud...

I already have a di-pole. A 102' G5RV on my roof. I'm building a second antenna because my current 150' long wire has fallen apart on the roof after being up there for three years. I have an ICE-180 balun that I can take off of that mess, so I figured I'd use that in the construction of something that can make use of it, like an inverted L. So far I just spent money on a new 6' ground rod and a 20 buck spool of antenna wire. Under 50 bucks total. Why the hell wont I get an effective ground here with a six foot ground rod ??? I always thought the ground here in this area had great conductivity. That is why there are so many MW transmitters here. BTW... My G5RV works very well from 5 megahertz to 10 megahertz. Is isn't so good below of above that. My 150' long wire was great for anything above 10 megahertz. Unbelievably, it was also very good for 3 megahertz to 4 megahertz. I have no idea why. The way I had that one grounded was, I'm sure, a poor way to do it. I have a 12 gauge wire going from the radio, up on the roof to the ICE-180 balun's ground, and then back down the house to a ground rod in the earth. The current ground rod is only 3' long iron bar. Don't ask me how, but it worked. Michael How about a Soviet active? http://www.naval.com/vpa.htm ;-) |
