Delta Loop Low Cost
All you need is a 6.2m of flexible wire, 1.1m of 75_Ohm coax, some electrical connector blocks and a length of rope to hang it from

50MHz-Lambda/2-Vertical
The matching circuit is the same as above with the following components, C 1 = 20 - 110 pF, variabel Mica capacitor,C 2 = 2 - 15 pF, variabel foil capacitor
50MHz-Yagis
The 50MHz-Yagis are designed with an impedance of 12.5 Ohm or 28 Ohm and some types with 50 Ohm impedance
6 & 2 Meter Square Copper Dipoles
A 2m square dipole, made from copper plumbing fittings and 1/2 inch copper water pipe
6 Meter 5/8 Wave Vertical Antenna
The vertical is loaded from the bottom with a coil wound on a previous block

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
