“Yes, BUT -- these are passive networks, and the response of all passive
networks depends upon the source Z and the load Z at each port. I'll bet your
measurements were for 50 ohm sources and 50 ohm loads. Real world antennas
differ widely from 50 ohms even when they are close to resonance on th

Hi Phil,
Thanks for the info. I read the product review.
I will try to find better combination of antenna connection to the ANT1/2/3
ports.
Local noise is very strong in my location, sometimes S7 to S9 in worst case. So
bigger antenna picks up more noise. When my 14MHz quad is connected to ANT1,
Hi Keith – Take a look at the measured KAT500 isolation numbers in the “Product

meters has a worst-case value of 36dB between ports 2-3 (wh
I am experiencing poor signal isolation between antenna ports of KAT500.

On selecting ANT1 or ANT2, I hear signal from ANT3 although signal level is
lower than ANT3.
