VHF/UHF Amplifiers

TE Systems 4452 430 - 440 MHz 180W

Selling my TE Systems 4452 430 - 440 MHz 180W amp as I have a higher power amp now and
have in general too much stuff! Serial number 5629. A few minor cosmetic blemishes but
otherwise VG condition. This is the model without the internal preamp (on 70cm, the preamp
should go a the antenna in any event).

Note I am also selling TE Systems 0552G, 2252G and 1452G amps and all will be listed here on
eHam over the next day or so.

Drive 10 25 Watts / Power Out 180 Watts Requires 13.8 VDC Amperes @ 30A N connectors.

TE Systems says:

These are linear amplifiers with drive power levels usable down to <.5 watt.

All amps are spectrally checked and are free of harmonics and spurious to -60dBc.

delay control.

T/R-switched amplifiers have user friendly controls are mounted on front panel with all RF and
DC cables attached out of sight on rear panel.

LED status lights on front continuously monitor the operating state of the unit.

Thermal shutdown protection built-in >+65°C. Full remote control capability is available; use

$479 plus shipping and insurance (your choice UPS or USPS or you pick up in Grand Junction
CO). Non-smoking shack. Paypal preferred but will take personal check (or cash if you pick up
in person). I can also personally deliver the amp to Visalia or Dayton Hamventions in the coming
