Design Principles of a M/LC Repeater Network
February 2004 5
two batteries are used with a 150 W repeater and four with a 300 W system, but you can always choose to
install four batteries in a 150 W system. (The battery box holds four.)
2.1.6 Lightning Protection
All M/LC repeaters come with some lightning protection. There are Polyphasors on the GPS and RADIO
RF inputs into the battery box. Also, power from the solar panels runs into a Delta lightning arrestor. All
chassis ground wires connect to one of the bolts at the base of the mast. However, the repeater uses no
lightning diverter at the top of the mast, nor does it use ground straps, or ground stake/rods.
If lightning is a concern at your installation, you can purchase the 302510 Lightning Protection Option
Kit from Modular for each mobile repeater. This kit includes the diverter at the top of the mast, ground
braids, copper straps, and a ground rod.
