Antenna 6 meter Links →
4 elementos para 6 metros
4 elements yagi antenna for experimentation in 50,110 MHz, 6 meter band
4 and 2 Element Quad Antennas for the 6m Band
This antenna is based on a design for a portable 2 element 6m Quad
45-70 MHz aerials for TV DX
To calculate the length of a half wave dipole at a given frequency, use the following simple formula: 468 divided by the frequency = half-wavelength in feet. 468/f MHZ = answer in feet
50Mhz 6 Element Yagi

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
