Dual antenna connection

I run a new coax from 6el 5m antenna and connected it to Ant2.
Ant1 is a 2el Steppir connected through Microham Power meter.
I was suprised to see that when I TX on Ant2 50mhz antenna, my power meter (that connected to Ant1) shows 0.011w and SWR 8.47. 
Any idea why I would see SWR reading from Ant 1 when I transmitting to Ant 2?
No other panadapters/slices active at that time, only slice A.
Thanks

Sounds like you have reflected power coming back from Ant1 and it’s feedline into the SWR meter and there’s no output power on Ant2; hence, high SWR ratio of reflected vs forward power.

Paul,
Thanks you for suggestion.
Will have to check how does it look at higher power.
Currently I just tested on 50mhz antenna with 100w from flex 6600.
Next thing to try to TX on 1.8-28mhz with Acom 2000a and see how it will impact the 50mhz.
If it will be an issue than will consider the filters.
