Is antenna isolation better in the Antenna Genius than in the 6600?
Assuming the same antenna setup, does the Antenna Genius provide better antenna isolation than a Flex 6600M? The Antenna Genius documentation indicates that it provides a minimum of 70dB isolation between ports. The 6600 documentation doesn't provide a specific number.
I currently have 3 antennas connected to my Flex 6600M at my QTH:
ANT1 - EFHW
ANT2 - Vertical dipole
RXA - Loop on Ground
It performs well as-is, but I am about to add in a TGXL and PGXL. As far as connections go, I don't "need" an Antenna Genius, but if it provides better antenna isolation it might be worth it.

here is an example of how good the port isolation is

Mike is referring to the 6600. You could ask him for a more exact figure.

That port-to-port isolation does sound great!
I once used a manual switch to select among radios, not antennas. This manual switch featured about 60dB port-to-port isolation, and I was very uncomfortable when 100W of TX was slamming the S-meter on the (disconnected and grounded) receivers. Selecting among antennae is far less-demanding.
It is hard to achieve good isolation like 90dB when there have to be some gaps inside - nice work!

Nice video Mike. My buddy Dave, W4WKU and I took our Flex 6400s to a Field Day site a few years ago. The nature of things put our doublet antennas broadside to each other and only about 100 yards apart. He ran 100 W and I ran 500 W. We did not hear a peep out of each other, even on harmonically related bands. We even worked the same bands occasionally (not intentionally!), one of us on CW, the other on SSB. My 500 W bothered him a bit (but it wasn't devastating), his 100 W bumped my noise floor a bit, but did not slow me down at all.
So even the 30 - 35 dB of isolation provided by the 6400 radios made it a really great Field Day.

Thank you, Mike. That video was a great example. I've never seen any warnings popup in SmartSDR so it looks like I am good with the built-in separation.

This may be a very basic question but if I buy a power genius and a tuner genius for my Flex 6600, do I also need an antenna genius and if so why? I’m using an OCF 135 ft dipole inverted V installation as my only antenna (apartment dwelling). Thanks 73 W6MIL0

You only need an Antenna Genius if you have multiple antennas to switch among.
