Antenne delta-loop 160- 80- 40- 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

Auto Tune Multi Band Delta Loop Antenna
The tuner cannot be tuned to an antenna of any size. The power to the part where the voltage is off has a high impedance and the change tends to be steep, making it difficult to tune
Corned Fed Delta Loop
The Delta Loop antenna is one of the famous magical antennas, but in reality, the Delta Loop antenna is not as magical as it's reputation. Despite its reputation as a Multi band antenna, it is a single band antenna. It can be somewhat tricky to make a Delta Loop
De Delta-Loop
A delta loop is a closed loop antenna that normally forms an isosceles triangle. If the delta loop is constructed as an isosceles triangle, it has a gain of approximately 0.5 dB relative to a dipole. The impedance will be around 70 ohms. If we flatten the triangle a little, the impedance can quickly rise to 100 ohms and more. The total length of the conductor can be calculated as follows: 306.3 / f f = frequency in MHz

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
