And who knows what other hare-brain idea comes tomorrow...
I get kind words about my HF signal, and generous reports on FT8 etc., so the question always comes up, "what is this antenna, and how much power from the linear?"
No amp, just a barefoot IC-7610 with 1.42 firmware, running DPD, standard HM-219 mic, and free Linux software for digital modes, RTTY, SSTV and logging.
The main antenna is a 20% off-center fan dipole suspended on glass insulators at about 90', well clear of vegetation. The elements are 10G insulated stranded copper, half-wave for 160m and 20m, verified with a mini 1300 VNA. The balun + common-mode choke is a Palomar 1:6 CB-6-1-1500EB. Coax is RG-213 throughout.
Lightning protection is by ARRL Insurance*, assisted by PolyPhaser IS-50UX-C0 gas discharge and blocking capacitor, grounded to a surrounding bonded 8 x eight-foot copper-clad grounding rods, also connected to the domestic supply ground. Additional protection is from heavy duty knife switches for the antenna and tuner control lines. The IC-7610 is protected additionally with a Paradan single Antenna Disconnect Actuator controlled by the ACC2 port of the IC-7610.
A single cable feeds an AH-730 remote tuner, to a Diamond MX610 duplexer, splitting HF to the fan dipole, and VHF to a 2-element Moxon at 40'.
So there it is, really just 100W and a wire.... *And yes, we had a direct strike, and ARRL Insurance is truly very good!
