Adding 30 and 40 meters to the 4 Element SteppIR
The first thing I did was to extend the fiberglass tubes to the 213 inch length specified
Antena multibanda G5RV
This is an adaptation of the antenna of reduced size to 80 and 40 meters, whose operation was a success.
Balanced Terminated Folded Dipole
Designed my btfd to operate on a minimum frequency of 1.8 mhz with an intended use spaning from 1.9 to 11.0 mhz

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
