Telex TR-1 Antenna Connection, Antenna Polarization, Distance between Antennas, Antenna Placement

Antenna Connection

The base station is supplied with two (2) antennas. One 1/2-wave antenna for Transmit and one 1/2-wave for Receive. The antennas have TNC male connectors.

The frequency range of the antennas should match the receiver and transmitter of the base station. Match the color code on the antenna with the color code on the base station.

Attach the transmit 1/2-wave antenna to the antenna input re- ceptacle labeled “TRAN” on the right side of the rear panel. The antenna should be vertically aligned.

Attach the receive 1/2-wave antenna to the antenna input re- ceptacle labeled “RCV” on the left side of the rear panel. The antenna should be vertically aligned.

Antenna Polarization

The Telex Wireless Intercom System is “Vertically Polarized”. This means both the transmitting and receiving antennas should operate in the vertical position.

Distance between Antennas

The distance between the base station’s receive and transmit antennas is not adjustable when the antennas are connected di- rectly on the back of the unit.

The antennas can be remoted for better signal path. A Telex coax assembly with remote antennas may be required. See “Accessory and Replacement Parts” section for ordering infor- mation.

NOTE: If your base station is to be located in a shielded rack mount enclosure or other poor RF location, you must remote the 1/2-wave antennas with coax assemblies. See “Accessories and Replacement Parts” section for remote mounting hard- ware.

Antenna Placement

Proper antenna placement probably has the most effect on your TELEX Wireless Intercom System’s overall perfor- mance. The following suggestions will result in optimum per- formance.

Proper placement of the beltpack can be critical. The antennas should be in the open. Bending the antennas up and placing the beltpack in a pocket, etc., will reduce system distance.

It is suggested that the unit be worn on the belt or pocket with both antenna’s vertical for best operating range and perfor- mance.
