Specifications:
Station Guardian provides critical monitoring and protection for transmission and antenna systems. This instrument continuously monitors and displays forward and reflected RF transmitted power and VSWR levels simultaneously on RF transmission lines. The system is equipped with visual alarms to warn of abnormal system conditions, and may be optionally equipped with switching relays to activate automatic standby switching.
The 410 series of indicators is mechanically similar to the SG-34 shown, except it contains the meter and switching circuits only. Both are available in a 19" rack-panel mount.

Designed for extending the range of 900 MHz wireless radio devices, Teletronics SmartAmp is particularly effective when used with Direct Sequence or Frequency Hopping Spread Spectrum radio modems. Built-in dynamic power sensor adjusts the RF power output level by reading the input signal power. Delivers maximum output power at various input levels while keeping the distortion at a minimum.Full output power of 1W is achieved with only 4mW input to the amplifier. Above 4mW input, the SmartAmp attenuates the input signal power and maintains the output power typically at 1W.Substantial discounts available for OEMs and large volume purchases.
