The Dishtronix web page for their amp, DX 2400L 1, makes the following
statement, " Beam antennas and multiband verticals are not designed for use
with a tuner."
This odd statement is made in the context of the company not offering an
automatic antenna tuner inside or external to this amplifier. That site goes
on to explain that wide range matching of an amp to various antennas ...which
may have higher swr like 3 or even 4 to one... should not be done; instead,
the amp user should make his antennas more resonant and with swr of 2 to 1 or
less. That passes the issue of amp matching antennas on to the antenna and
handily off the task of the amp. I have had a few resonant antennas but none
which presented a flat swr over the whole of one band. Makes me go huummmm.
I guess if one can afford the 2400L, one should be able to afford a whole lot
of antennas which can then present a flat swr to this amplifier regardless of
frequency. Or a few StepIRs, maybe?
Am I being too hard on Dishtronix's web site wording?
Added note... an Alpha 9500 added to the cost of their Model 4040 high power
auto tuner will be less than the DX 2400, QSK version. I am making these notes
in the context of this reflector's continuing conversation about solid state
amplifiers.
