Note that the PMU connector used in the TBA2241 and TBA2242 cables
was changed in August 2004 to match the change of connector in the PMU.
The old cables are still available under Tait part numbers 219-02895-00
(single) and 219-02896-00 (double). Contact your nearest Tait Dealer or

7.3 RF Connections
Important The PA may be damaged if the load is removed or switched
while the PA is transmitting.
To protect the PA output stage from load transients (i.e. switching or
removing the load), we recommend that you fit an isolator between the PA
and the load. Fit the isolator as close as possible to the RF output connector
on the PA. Do not connect any switching or combining equipment
between the isolator and the PA.
The RF input to the TB8100 BSS is via the lower BNC/TNC connector
on the rear panel of the reciter. The RF output is via the N-type connector
on the rear panel of the PA (refer to Figure 7.4 on page 107).
We recommend that you use dual-screened coaxial cable such as RG223 for
the BNC/TNC connections, and RG214 for the N-type connections.
When the base station is used in simplex mode using a single antenna with
a coaxial changeover relay, the isolation of this relay must be ≥40dB.
