Transmitting loop for 7 MHz
Large-diameter plastic support frame surrounded by thin layer of copper
A Stealthy 75 meter Antenna
The 75 meter dipole was put up to meet the need for making contacts with friends in the Southwest and Southern California to be put up so no one can see it from the surrounding neighborhood
A Stealthy HF Coat Hanger Antenna
You're looking at a 110 foot inverted-V, fed with homebrew ladder line
Antennas for Limited Spaces
Some problems that while not unique to Florida are certainly more pronounced here Lots tend to be small, often less than 2000 square feet.

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
