Hi-Z Port delivers as advertised using 20M longwire directly connected (No 9:1).
Port A using a Scanking 0.05 to 2000 Mhz discone really delivers the goods! Not quite up to the longwire/Hi-Z although under certain conditions it can actually sometimes improve on that (of course everyone's situations differ).
Port B using the above discone does not perform anything like as well below about 4 Mhz as when connected to Port A.
In fact, connected to Port A the discone receives a great signal on 198 Khz, whilst on Port B virtually no or only a weak and corrupt one.
I have an active min-whip on order that I intended to connect to Port B, but am wondering whether in fact I would be better to connect this to A given the differing performances.
Any suggestions as to why there should be such differences between Port A an B would be very welcome (Bias T not in use).
