Attic hf dipole.
With his antenna matching unit providing an acceptable match he s on the air making contacts.
Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space.
If you need more room consider zig zaging your wire just keep your turns at 90 degrees or more.
The infamous attic dipole.
Again run your dipole as far away from metal as possible.
Dipole lengths 1 2 wave antenna 468 feet freq mhz.
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.
There are a lot of dipoles in attics out there the big limiting factor here is the size of your attic.
Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.
Dipole antennas do not forget the dipole antenna for a single and multi band use.
Also commercial multiband or shortened dipoles work well.
The better your antenna the more success you will have making contacts.
