Mosley beam for 10, 15, and 20 meters.
I
modified the Mosley antenna to include a choke balun and a quick disconnect
outlet. While the choke balun is not a true balun, it does provide some balance
to the signal reaching the antenna and reduces RF in the shack. I am currently
running the antenna with the ground strap disconnected. That reduces power lost
in the mast itself. While the removal of the ground strap did appear to increase
the SWR at the low end of each band, reports (so far) have indicated an
improvement in signal relative to the vertical antenna. The down side is that I
have to use the rig antenna tuner to reduce SWR, but all bands are less than
3:1, making them tunable by the Yaesu transceiver.
The quick disconnect will allow me to quickly remove the beam if I choose to crank it down for anticipated high wind (i.e. - hurricane).
