Elad AMS-33: transmit capable cross bar switch for HF-150MHz
AMS-33 is an antenna cross bar switch (matrix switch) which allows you
to connect any 3 antennas to any 3 radios. The operation is simple as it
can get - with the push of a button all six possible combinations are
stepped through. Another, seventh combination is available as "all off".
|Combination 1||Combination 2||Combination 3|
|Combination 4||Combination 5||Combination 6|
AMS-33 is useable for transmit operations (not just reception) from DC
to 150MHz. The max. power is 500W PEP at 30MHz. Insertion loss is 0.3dB
at 50MHz and 0.9dB at 145MHz. Cross talk attenuation between outputs is
at least 35dB at 145MHz.
