1+1 Intermodulation Products for Multiple HS or
NP Radios with Common Antenna Feedline
For single antenna configurations, to avoid creation of intermodulation
conversion products in the ferrite devices which can cause threshold
degradation in a local receiver, the following rule must be observed.
The intermodulation frequency products that result from combining two or
more transmitter frequencies on a common antenna feeder must be 48 MHz or
more above or below each of the receiver frequencies on that antenna feeder.
Note that all possible combinations must be taken into account (for example,
2A-B, 2B-D, A+B-C, C+D-B, and so forth).

Frequency Bands

Constellation radios are available in 6, 7, 8, 10, and 11 GHz frequency bands.
The following tables show the frequency bands for the various countries.
