I have the CN-901 HP3, a BIRD 43 with several elements and a BIRD 4410A with the 4410-4 element. Both BIRD meters seem to be "right-on" with each other and the 901 indicates almost ten watts less than the BIRD meters.
I agree, the 901 is a good (multi-function) shack meter and I like the external 12V power source because there is no battery level indicator on the BIRD 43 but the BIRD 4410A has a battery level indicator.
Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
