50MHz-Yagis
The 50MHz-Yagis are designed with an impedance of 12.5 Ohm or 28 Ohm and some types with 50 Ohm impedance

Antenna 6 meter Links →
The mighty wide six metre dipole
Simple 50 ohm coaxial feed design, no Antenna Tuning Unit required, Wide Bandwidth - 50 . 00 to 52 . 00 Megahertz
The X-antenna antenna for portable work on 6m
The 4 rods go through holes grommet sealed in a small round plastic box. The rods I used have 10 sections with a maximum diameter at the base of 9.5mm. When un-extended they are 16.5cm in length and 131cm when extended
Tonnà 5 Elementi 50 MHz: modifica del dipolo
La 5 el. Tonna e' un'antenna con un buon rapporto prezzo/prestazioni, inoltre e' discretamente robusta e facile da assemblare per un uso portatile
Una Yagi a 6 elementi per i 6 metri
L'antenna, una sei elementi lunga poco meno di sei metri, il boom in tubo di alluminio del diametro di 40mm

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
