I'd expect that to work. However, the issue is that you probably had
considerably more signal period on the amped BOG, so you need to attenuate
it to get a back null.
Ideally with these Phased BOG Systems you're looking to null back end QRM
while not reducing forward DX and hopefully the forward DX can actually
gain a couple dB signal from the combination of two antennas.
Here's an example, using the Quantum Phaser, (forgive me, Nick and Colin,
but I cannot get your phaser to work this well here and will wrap it back
up and take to P.O Saturday) KYW blasting in with 1062 TA carrier.
Reversing phase just about killed KYW to reveal XEEP and the TA carrier was
also basically gone. Mini-BOGs aimed 32 deg. 73 KAZ Barrington IL
