Instead staple a closed tie wrap forming a loop at each stapling point.
Long wire antenna in attic.
6 captain kilowatt oct 5 2009.
Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space.
The ge 33692 attic mount hd antenna is a notable example of an antenna specially designed for placement in the attic.
The most economical and highly recommended measure is to insulate the bare antenna wire.
The most important is the physical size of the antenna used then its radiation pattern.
The equivalent long wire is twice as long.
The 1 2l dipole radiator driven element is 10 m long or so.
Absolutely no difference from 100 ft.
Ok have 300 ft in the attic.
Going to experiment with some stuff outside.
This was installed at a previous qth i will be the first or millionth remember i m from fl to affirm that the antenna is the determining factor for success when it comes to one s station set up.
Green is the 15m long wire bicone antenna mounted in the loft yellow is a 40m long doublet fed with 450 ohm ladder line and an auto atu at the base blue is the 40m long ladder line fed doublet strapped as a tee and fed against 16 ground radials using an auto atu at the base.
This antenna has all the reception power of an outdoor antenna but features a curved metal frame of reflectors that are designed for fitting easily into smaller attic spaces.
Unless you have it straightened out 1000 feet will be no better than 100 feet the signal cancelation that takes place along a jumbled up wire antenna is quite appreciable.
Mac af4ps fp 51 note.
With his antenna matching unit providing an acceptable match he s on the air making contacts.
The infamous attic dipole.
Zigzagging a bunch of wire in the attic will pick up distant radio signals poorly but electromagnetic interference emi from household electronics very well.
Clearstream 4v hdtv antenna.
Let s imagine a hf antenna resonant on the 20 meters band.
The better your antenna the more success you will have making contacts.
It s a long way from the rabbit ear designs you might think of when picturing indoor antennas and much cooler looking than the metal contraptions often found outdoors.
Run the wire through the loops and let it hang slightly away from the wooden rafters.
