An Attic Coaxial-Cable Trap Dipole
A coaxial-cable trap dipole antenna installed in the attic provides a surprisingly effective solution to HF operation on the 10, 15, 20, 30, 40, and 80 meter

G5RV Antenna
The G5RV antenna is probably one of the most maligned antennas in the world
G5RV Formula a simple multiband antenna
Most people think that the famous G5RV antenna was designed as a multi-band antenna, but in fact, it was actually designed as a three - half waves in phase antenna for 14 Mhz
G5RV multi-band antenna
The G5RV, with its special feeder arrangement ladder line, is a multi-band centre-fed antenna capable of very efficient operation on all HF
How High should my Dipole be
I frequently hear the question: how high should my dipole be? Or alternatively, will my dipole work well at this or that height?

Antenna switch arduino for icom IC-7300 A solution built around an arduino nano and one of the readily available four relay switching boards
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
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
