When considering intermittent co-channel tropospheric interference from other
TV signals, not necessarily identical in their emission characteristics, a basic
protection ratio of 45 dB for a single interference entry is considered appropriate;
...

It is also necessary to define an adjacent channel protection ratio, the ratio of
power in the adjacent channel to that in an wanted channel which just permits
acceptable service. (Note that the definition is the inverse of that for the co-
channel ...

Protection ratio The protection ratio (PR) is the required RF signal to interference
ratio; it depends on the required signal quality, the transmission system, the
receiver characteristics and the personal perceptiveness of the consumer.

For this reason, the protection ratio is relaxed to 30 dB for tropospheric
interference. As an example, consider the 1 MW Crystal Palace television
transmitter located on high ground near Croydon. It has a 64 dBμV m−1 service
area with a ...
