20 Meter Dipole In Attic

This was found to be quieter and made the antenna less sensitive to frequency changes.

20 meter dipole in attic. This was okay but appeared noisy. I initially feed the dipole directly with a 1 1 balun and rg58 coax. The infamous attic dipole. Look 95 of the contacts are below 20 degrees and compare the vertical and dipole patterns if the attic area is not large enough to accommodate an almost full size dipole simply erect as much of the antenna as possible in a straight line then bend the ends of the dipole up down or sideways from the main portion of the system.

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. 20 mtr 40 mtr 80 mtr. A coaxial cable trap dipole antenna installed in the attic provides a surprisinglyeffective solution to hf operation on the 10 15 20 30 40 and 80 meteramateur bands at a qth with restrictive covenants that prohibit outsideantennas. Magnetic loops this version is 3 5 ft on each side can be tuned from 20 to 10 meters one band at a time larger versions will work on 80 or 40.

To fit this antenna in an attic space i used an inverted v configuration. Dipole easy and cheap to build can be made with small gauge wire. An attic coaxial cable trap dipole for 10 15 20 30 40 and 80 meters. Could be mounted in attic or in back yard out of sight coax to station 40 mtr pair.
