Bouvet , that is.
Having small place to use for this project the choice seemed obvious - full size single K9AY loop switchable N-S directions.
Suprisingly antenna performed very well, even and installed close to metal garden garage and house on the side. Termination resistance matrix in lack of Vactrol were made according to OE7OPJ design - worked FB. Difference between N-S direction with proper termination was more than 1S.
And of course much less noise.
In result, some good DX worked on 80 and 40m not even decodable on InvVee or wire Inv L antenna.
Anyway, having separate RX antenna without automated front end saving and TX inhibit is a real adventure :-) But when You forget it's a real life... sometimes things can go wrong :-)
Well, next time I will build bigger box and bigger termination resistors.
