Hello Folks! I'm looking at the 90' version of the folded dipole antenna made by B&W for Navy MARS use. This would replace my HORRIBLE Van Gordon G5RV (I guess everyone needs to try one to believe th
B & W makes some really good antennas, HOWEVER>>> as you know all multi-band antenna are one trade off or another. The way B & W gets that folded dipole to play on all bands with less than 2:1 SWR is
The B&W site says this.... Q: Does the terminator (balancing network) create losses? No, it does not create losses. It dissipates losses from the ever present lack of perfect antenna efficiency. No a
The G5RV when configured and installed properly is actually a pretty good antenna. The current models for sale that have a balun and coax to the radio are not really G5RV's. The original G5RV, develo
About 10 years ago, I built an HF communications system for the state law enforcement agency I was working for in Florida. We had frequencies scattered from 6 MHz to 13 MHz and the equipment was to b
Roger D Johnson wrote: original G5RV, developed by Louis Varney, was fed with balanced line through a tuner. The balanced line kept losses low and the tuner enabled operation across many ham bands. 7
I picked up the Yaesu version of this design Theirs is YA-30, a little shorter than B&W's antenna Got it due to the fact that I have little space to hang A good sized antenna for lower band work. I a
I think the definitive analysis of this antenna has been done by W4RNL: http://www.cebik.com/wbfd.html The analysis shows that on 40 through 10 the gain is about -6 dB compared to the same length dou
Gee, I was generous... I said in a personal email that the efficiency of the B&W terminated folded dipole was typically between 25 and 50%! It seems to be a bit worse than that. They really are "dumm
