Long wire antenna in attic.
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.
Absolutely no difference from 100 ft.
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.
Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.
Let s imagine a hf antenna resonant on the 20 meters band.
The ge 33692 attic mount hd antenna is a notable example of an antenna specially designed for placement in the attic.
With his antenna matching unit providing an acceptable match he s on the air making contacts.
Ok have 300 ft in the attic.
The most economical and highly recommended measure is to insulate the bare antenna wire.
Instead staple a closed tie wrap forming a loop at each stapling point.
Feeding a dipole off center makes the feed line act as part of the antenna unbalanced load thus it will pick up even more emi on the feed line.

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.
The equivalent long wire is twice as long.
The 1 2l dipole radiator driven element is 10 m long or so.
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.
Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space.
The better your antenna the more success you will have making contacts.
The infamous attic dipole.
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.
Clearstream 4v hdtv antenna.
Zigzagging a bunch of wire in the attic will pick up distant radio signals poorly but electromagnetic interference emi from household electronics very well.
Going to experiment with some stuff outside.
