The system consists of the following blocks:
4) 13.8V 5A Switched Mode power supply
5) Simple 5V regulator based on the 7805 chip (TO220 package).
The RF output is connected to a 30m length of RG58 coax. At the far end, the coax connects to a balun at the centre of a simple 30m wire dipole (no tuners etc). No attempt has been made to trim the dipole for proper resonance, so this system is far from perfect. Nevertheless it works well. I use it on bands from 160m to 10m even though the dipole is for 30m. Obviously the other bands work less well than 30m.
