Antenna 6 meter Links →
6m 50Mhz Long wire antenna
From the transmitter or transceiver, you go to an antenna tuner via coaxial cable. The tuner is placed at the base of the antenna, not at your operating position
6m beam antennas
This type of antenna is a rather handsome one, so you can use it for portable operation
A Hairpin match for the 5 ele Tonna for 50 MHz
By changing the impedance of the driven element to 200 Ohms, it is possible to use a 1:4 halfwave balun to match the antenna properly and to make sure that the symmetry is also properly taken care of
A portable three element 6M yagi
settled for 12.5mm round hollow tubing in 2M lengths, for the main elements, with the next smaller size 10mm

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
