Long Wire Antenna In Attic

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.

Long wire antenna in attic.

6 captain kilowatt oct 5 2009. Run the wire through the loops and let it hang slightly away from the wooden rafters. Instead staple a closed tie wrap forming a loop at each stapling point. 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 1 2l dipole radiator driven element is 10 m long or so. The better your antenna the more success you will have making contacts. Going to experiment with some stuff outside.

With his antenna matching unit providing an acceptable match he s on the air making contacts. 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. 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. Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.

The equivalent long wire is twice as long. Absolutely no difference from 100 ft.

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 most important is the physical size of the antenna used then its radiation pattern. Let s imagine a hf antenna resonant on the 20 meters band. The infamous attic dipole.
