Antenna
The Alliance Tenna-Rotor® consists of two units: the rotor unit, which mounts on the mast below the antenna, and the control box, which is placed on or about the TV receiver. These are interconnected by a four- or five-conductor cable. The theory of operation concerns two separate circuits. The first is the power circuit, which in all Tenna-Rotors® transmits the power that actuates the motor and rotates the antenna. The second is the indicator or signal circuit, which reports the roto ...

Level Meter
The CN-400 series is a high quality instrument with a unique feature which makes tedious measurements of SWR and power during antenna tests, matching and tuning of transmitters a breeze. SWR and power indicators are installed in one meter unit. One scale will indicate Forward Power, another scale Reflected Power and SWR is indicated at the crossing point of the 2 needles. This unique feature makes it possible to read Forward Power. Reflected Power and SWR all at the same time. " ...
