Hi Bill,

If there's no KAT3 installed, you still have a few options.

Normally, the sub will share the RF path of the main receiver, and that 
includes the RX ANT. I.e., if the main RX is running from the RX 
antenna jack, then the sub will, too, if it's sharing RF.

You can switch the KRX3 to its auxiliary input, but if you don't have a 
KAT3, the question is what to connect it to. The present KXV3 doesn't 
have provisions for routing RX ANT only to the sub. But there are three 
other sources you could use for the KRX3's aux input: (1) the SO239 at 
ANT2 (normally supplied only with the KAT3, but you could order one and 
install it just for the sub); (2) a BNC jack, below ANT2 (labeled "AUX 
RF" and not normally supplied, but we could provide one on request); 
(3) the BNC jack on the KXV3 normally targeted as the buffered I.F. 
output (but you'd lose I.F. out capability).

Also, if there's enough demand for an antenna-switch-only version of 
the KAT3, we could offer one in the future. You'd then be able to 
connect the KRX3 to the unused antenna jack, as with the KAT3.

73,
Wayne
