Frequency Bands
The RKP-4B system operates in TV channels 16 to 36 and 38
to 59. This is the frequency range of 482 to 608 MHz and 614
MHz to 746 MHz. The band, TV channels and frequencies are
shown in Table 2. Most bands are 18 MHz wide, however
band 7 is 24 MHz wide.
Bands F to E are always base transmit bands (beltpack receive
bands). Bands 1 to 7 are always base receive bands (beltpack
transmit bands). Thus an A2 base station would be comprised
of an A band transmitter paired with a 2 band receiver.
Band Pairing for Systems
All band pairs cannot be made into a system (a single system
is comprised of a base and beltpack). Table 1 show the avail-
able band parings.
Table 1
Available Band parings
In Table 1 it can been seen that a C base station transmit band
can be paired with 4, 5, 6 or 7 receive bands. However, a C3
unit cannot be made. This is because a certain amount of fre-
quency separation between transmit and receive bands is
required for good transmit and receive operation. If they are
too close the RF performance of the system is reduced.
