Quarter wave 80 meter vertical antenna

Quarter wave 80 meter vertical antenna An RF switch is convieniently mounted at the top to switch between 80 and 160 Meter operation

The Folded Dipole

The Folded Dipole The Folded Dipole is not used much amongst Radio amateurs, probably due to the fact that this antenna uses twice as much wire as a single-wire dipole

50 MHz preamp Gain 26dB with the BFG135

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
