SG-235 Smartuner - SGC

SG-235 Manualantenna and a strongly built (Mylar or nylon) kite.Remember that when a mast comes down, you have easy access to the highvoltage feedline which may be secured to a kite antenna. Offshore power boatscan use this antenna as well, since 10-20 knot winds are almost always availablewhen underway at sea.5.5.1 Kite AntennaBox, delta, or conventional kiteUse string to post for strain reliefÑdo not tiekite wie to coupler without strain relief100 feet ofstring30 to 70 feet of wire30 to 70 feet of wireground conductor (counterpoise)JumperStringCouplerNote: The counterpoise may be underwater if installed on abeach or from a vessel at sea. If an underwater counterpoise isused, tuning may change with tide changes in shallow waters.This type of antenna has been run for hours in tropical tradewinds with excellent results.Post or stake5.7 Tactical InstallationsOver the course of nearly 30 years of HF, SGC equipment has been used everywherefrom camelback in the desert to Antarctic expeditions. Along the waywe have collected a number of tips to get maximum system performance fromyour radio system when you are operating in a tactical or disaster situation.These tips, by the way, also apply when you go camping or are involved inamateur radio Field Day activities:5.8 TACTICAL Antenna SupportsExcept for a barren desert, just about all landscapes have structures (naturaland man made) which can be used for antenna supports. All it usually takes isseveral hundred feet of rope and some creativity. Here are some examples toconsider. If you wonder which structure would work best remember the onewith the greatest height and greatest distance from grounded metal will generallygive the best performance.1. Natural rock formations such as cliffs and bluffs.2. Tall trees.3. Water towers.4. Church spires and minarets of mosques.SGC Inc. SGC Building, 13737 S.E. 26th St. Bellevue, WA 98005 USAP.O.
