80 Meter 3-element Vertical Yagi
Coil Q is not critical since the loss is low. Even at a kilowatt the estimated dissipation is less than 10 watts

Antenna 80 meter Links →
80m Band Top using 2 elevated radials
The TLV80 antenna is mounted on a Fiberglas Teleskop Mast Height of mast is 8 meters
80 m 3/4 wave LLV
The left Vertical wire is 180 degrees out of phase with the middle and right Vertical wire
Dipolo rotativo delta para 80 metros
The rotating dipole for 80 meters has a length of 20 meters, its weight reaches 20kg
The triple 4-square project antenna
The 40m 4-square will be centered in the 80m one, which will be centered in the 160m 4-square. hence the triple 4-square

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
