A Balanced Balanced Antenna Tuner



Balanced Balanced Antenna Tuner
    As a rule of thumb, a balun should have about 4 times as many reactive ohms as the resistive ohms of the load. This means that for use with a 600ohm balanced load, the balun should have a secondary winding reactance of about 2400ohm

HF-6M Antenna Tuner Preselector
Frequency range: 2Mc...52Mc 180m band depending on the mismatch of the antenna used and-or maximum inductance. Experimenting with the coils can be desirable

HF Automatic tuner
The atu is composed essentially of relays commanding inductors and capacitors

I built a ZM-2 QRP Antenna tuner
The Emtech ZM-2 Antenna Tuner is a nifty little portable transmatch for QRP

30 meter receiver low power qrss beacons and psk31

30 meter receiver low power qrss beacons and psk31 That is possible by using a low CW speed. QRS mean reduce your CW speed. With that extra S of QRSS they want to indicate that it is really a very low CW speed

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 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
