8. SPECIFICATIONS
8.1. Parameters
8.1.1. Operating Frequency Range
Continuous from 1.8 to 30 and from 50 to 54 MHz, extensions and changes on request.
8.1.2. Minimum Range of the Matched Impedances (at Each of the Four Antenna Outputs)
All impedances with SWR from 1:1 to 3:1 towards 50 Ohm, any phase angle, unbalanced input and output.
For some frequencies and impedances, matching is possible at SWR above 3:1 at the
antenna output (up to 10:1), but the maximum allowed power is reduced (see Section
8.1.3 Maximum Allowed Input Power
8.1.3. Maximum Allowed Input Power
(PEP, Mean or Continuous Carrier, Without Mode Limitation)
The maximum permissible input power is reduced gradually as per
tuner as function of the antenna SWR
