Walton 48 VAC Heater for 0.6 to 1.2-meter Antennas
The 48VAC system was designed for sites with no AC power to the antenna. This system requires no conduit or wire from the power source to the antenna, and can be installed without the need for an electrician. Number 8/2 conductor 150 volt cable is used form the transformer to the antenna. The transformer can be located (plugs into wall outlet) up to 500 feet from the antenna. Electrical cable can be installed with the RF Cable.
Power to the heater is 48 VAC, which is supplied to the 800 Watt element, and rectified for the 48 VDC blower motor. The system is controlled with an on/off switch on the transformer assembly.
The system should be turned on in the fall, and off in the spring. The blower will operate continually while the switch is on. There is a thermostat in the heater, which turns on the heater element whenever the outside temperature falls below a pre-set temperature range.
