Like the photo!!( military base?!!
Was looking at similar on Cornwall coast..ex or maybe still used massive towers..over looking sea..there is more than one..Mary even says yes to buying one!!( once we sell house here in london.not yet though...)
Dont have the space for lots of loops.nor wife permission..
Could get 3-4 small 1m up, but really closely spaced..all cardioid maybe..phase them together and then against another noise loop..( cardioid loops on own will not null out noise due to direction of local noise in relation to where i want them aiming.)
So how to combine 4 loops in phase without having massive loss and spending £££? (Google time.)
Martin Chris any thoughts??
Also Chris..how about designing a higher (Lf) gain preamp optimised for the higher inductance cardioid loop? (Aimed at low band users..)
