40 Meter Parasitic Delta Loop Array
On 40 meters, my experience is that you need at least 20 dB of F/B ratio in order to be able to turn down European broadcasters enough to be able to hear the west coast stations, especially the west coast stations with dipoles and 100 watts

Antenna Delta Loop Links →
Inverted Dipole Delta Loop
For relays 160m 1 and 4 are energized, the antenna works as a folded dipole
L'Antenne Delta Loop
To calculate a Delta - Loop antenna the formula is relatively simple: we take the formula 1005 / F, here if we want the Delta Loop to be qrv any Band it must be calculated on the lowest frequency, we take as an example the 3,500 Khz
Antenne delta-loop 160, le 80, le 40 et le 30m
My delta measures 166m perimeter, has the shape of an isosceles triangle 2 identical sides are horizontal and is located at 18m from the ground, I use this antenna delta loop for my HF connections, and in particular for the 160s, 80s, 40 and 30 m

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
