Hw do u fasten the poles to the boom?
-- Listen to Alternative News and Conversation You Won't Hear On Commercial Radio. Visit http://live365.com/stations/pascoradio YOU HAVE BEEN WARNED! First Time Users May Be asked To Do A 1 Time Setup. " wrote in message news:mDtjd.310793$wV.66943@attbi_s54... ANTENNA CONSTRUCTION MATERIALS I use fishing poles for all my antenna experimentation. I thought supplying the following info would be of interest to antenna builders on this news group. I now see fishing pole antenna manufacturing as the prime method and not as a "make do" in place of conventional aluminum tube construction REASONS ALUMINUM (aluminium for U.K. builders) My aluminum rescources always seem to miss a required diameter. Clamps used to secure element portions always increased susceptability to ice build up Aircraft style tubing increasingly expensive Elements with electrically faulty connections. Pre built antenna prices are now rediculous thus new avenues are required for emerging hams. FISHING POLE. A 20 foot telescopic fishing pole can be used as a standard for all types of antennas without permanent mutilation. Cost per pole is $10 ( $2 if purchased in quantity China FOB ) Weight is 1 lb Material fiberglass with shellac outer protection No element clamp requirements Taper is perfect No ice build up. Pre sticky coat aluminum foil rolls readily available at hardware stores. Elements are electrically continuous as foil is applied lengthwise Foil length does not have to be physical element length Foil can be readily removed if required using heat gun or hair drier Boom to mast materials need not be metallic because of lightness of element Telescopic assemblies a breese to store. Boom materials are more optional and plentiful Rotor costs drop . LENGTH OF USE About ten years of continual antenna experience Temperature extremes 95 F to -20 F Breakdown and reassembly rotations numerable. Max number of elements used on one installation, 13 elements on a 80 foot boom.(20 metres, total element wt was 26 lbs) Regards Art |
