... the bare metal is exposed. Insulated towers should have a static drain choke connected between the feedline and the station ground. Insulated towers should have two 12-foot loops in the feedline between the tower and the transmitter housing. Cadwelding the connections is recommended. All tower attachments should be grounded to the tower, and these connections should be inspected annually, since poor connections can cause severe harm to equipment. Power lines must be protected with surge arrestors and line chokes. Phone lines should be protected with MOVs (Metal Oxide Varistors) . In lightning zones 6 or higher, lightning dissipation systems are highly recommended. It is prudent to have all grounding and lightning dissipation work be done by a professional lightning-abatement firm. 3. ICE. Two types of ice cause problems. Rime ice is similar to what ... found in a refrigerator. It weighs about 17 pounds per cubic foot and is quite porous. Glaze ice is different, and occurs only in certain geographic areas and elevations where the temperatures drop below 32 degrees. It is quite common in lower latitudes; it accumulates when there is a slight drizzle. This type of ice has a density of 54 pounds per cubic foot. A failure to install de-icing equipment results in excess weight and will cause increased wind resistance, resulting in possible tower failure. A single icing episode can produce damage to the tower, antenna, feedline, and associated structures simultaneously. Ice cracker cones are effective in protecting the guy wire grips. Ice bridges protect attachments from falling ice, including transmission lines leading from the tower to the transmitter building. Ice shields are inexpensive ...
