At 80′ – I can rotate the second KY6R 40M loop
I have a choice – I can have the second loop at 100 feet (where it would have to be fixed) with a bit better performance than at 80′ (where I can rotate the second loop). I’ll choose to rotate the second loop because the performance is not that far down, and rotating the antenna is a HUGE improvement. The gain isn’t different, but the RDF drops just a little – which means its not a big deal. In fact, because rotating adds in an important “dimension” (physical on top of the NCC-2’s electrical rotation), I will be able to have many ways to combat noise and also have great 40M dual stereo diversity reception.
At 100′ I can’t rotate the antenna but it would be a bit better (RDF) performance wise – but the same gain, F/B and pattern
I’ve decided to use Wellbrook remote pre-amps on each antenna, and to also rotate two at 80′. I’ll use the NCC-2 with no pre-amp or Bias T to the antenna – just as a phasing unit for two antennas and into the K3 RX IN port.
