[RFI] EMI resistant phones

I can't vouch for RS products particularly, but I think the "cordless
phone" approach is a good one for RFI considerations. The latest
digital phones operate in "networks". I have a 2.4 GHz digital base
that supports 3 handsets. Other models (5 GHz) support up to 5
handsets, AFAIK. I would stay away from 900 MHz & lower phones,
because of privacy issues, etc.
The advantage is that you only have to RFI-suppress the base station,
if there is a problem. You can locate it away from antennas and feed
lines. Any trouble is easily handled with ferrite toroids for the
power & telco lines. The handsets normally don't care about ham RF.
My 2.4 GHz unit even works right next to my microwave oven. I have
also not seen any problems with my nearby WiFi equipment.
