I just read the Joel Hallas, W1ZR article - "The 43 foot vertical monopole
- What's the magic?". It was very interesting! The coax losses are worse
than I imagined, up to 8dB though 100 feet of RG-213, and as my model
showed the radiation is very high above 20m. Certainly a relay to
electrically shorten the antenna would help 15m and 10m.

I always wondered why someone would pay $400- $500 for a '43 foot
vertical' when you can hang about $1.50 worth of wire in a tree and do
the same thing.
We had one of those for FD and it was not a very good antenna. 73
