QRP 80 Metre Slinky Dipole
the antenna always had to be mounted in the attic because no antennas are allowed to my QTH
Broad Band 80 & 40 meter bowtie dipole
This article is meant to address this issue with a design that is mechanically sensible

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
