The EASY and CHEAP HAM RADIO APARTMENT ANTENNA perfect for new hams

Another proud product from Ten-Tec. Nice Ten-Tec 420 Hercules II HF Ham Radio Linear Amplifier Solid-State /Mobile. I’m using a Astron 70 AMP power supply, which handles 500 watts just fine. The optional Model 9420 115/220 Vac power supply is in a separate utility enclosure and connects to the RF deck using a 6 foot power cable.
