4el. Hentenna for 50MHz
Hentenna has 3dBd gain with the unit as allowed. And it wins by 2 dB compared to the simple quad a loop element

Antenna 6 meter Links →
Einfache DeltaLoop fur 6m
The circumference of the loop is 6,1m wire. Connected in this way, it is vertically polarized
Hentenna for the 6m band
The Hentenna performs better than my commercial Al-pipe dipole. Moreover it is easier to transport and/or store anyway
L'antenne 6M
A double dipole fixed on a boom in the shape of H, which I will call cell. Each element 2 per cell is controlled by gamma match synchronized using a phase shift line
Six element antenna for the 50 MHz
Six element antenna. Gain is about 0,6 dB higher, but the main optimization is the front/back ratio

Antenna switch arduino for icom IC-7300 A solution built around an arduino nano and one of the readily available four relay switching boards
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
