Abstract

The system is for use with an AM transmission tower and comprises: a LED light mounted in use on the tower; a photocell; a LED beacon mounted in use on the tower; a controller; an RF choke interposed between and operatively coupling the beacon and the controller; and an RF choke interposed between and operatively coupling the photocell and the controller.

Claims

1. An improved system for lighting a tower, the system being of the type including red LED lights on the tower, a white LED light on the beacon, a photocell, a controller operatively coupled to the lights and photocell to operate the lights responsive to the photocell and an RF choke interposed between the beacon light and the controller to isolate the controller from the RF energy on the tower, the improvement comprising:

a further RF choke interposed between (i) the input power and the controller and (ii) between the photocell and the controller.

5. Use of the improved system of claim 1 for illuminating an AM transmission tower.

2. A system for use with an AM transmission tower and an ATU building, the system comprising:

a red LED double obstruction light mounted in use on the tower;

a photocell;

a white LED beacon mounted in use on the tower;

in the ATU building, a controller;

an RF choke interposed between and operatively coupling the beacon and the controller; and

an RF choke interposed between and operatively coupling the photocell and the controller.

3. The system of claim 2, wherein the RF choke interposed between and operatively coupling the photocell and the controller is also

interposed between and operatively coupling the controller and controller input power;

and

interposed between and operatively coupling the double obstruction light and the controller.

4. The system of claim 2 or 3, wherein a double obstruction light RF choke is interposed between

the double obstruction light;

and

the RF choke interposed between the photocell and the controller.
