Attic Hf Dipole

Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.

Attic hf dipole.

Mac af4ps fp 51 note. Do not forget the dipole antenna for a single and multi band use. Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space. The infamous attic dipole.

The better your antenna the more success you will have making contacts. 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. This will provide me a means of reaching out to the world while i save my pennies and look for a good deal on a multi band yagi uda hf antenna and possibly a different tower too. Again run your dipole as far away from metal as possible.

Also commercial multiband or shortened dipoles work well. Ladder line fed dipoles are ideal for attic use assuming that you can route the ladder line to your radio without too much metal contact. In the case of the ladder line dipole just make it as long as possible and stuff it into your attic any way you can. With his antenna matching unit providing an acceptable match he s on the air making contacts.

There are a lot of dipoles in attics out there the big limiting factor here is the size of your attic. Dipoles are one of the simplest antennas to build or construct and erect for the hf amateur radio bands and on top of this they can be very effective. Dipoles are widely used on bands like 80 metres 40 metres 20 metres 15 metres and 10 metres where they can provide excellent levels of performance. A project which i ve been meaning to complete for a very long time is to place a dipole antenna in the attic space of our house.

An auto tuner in the attic can work but you need a lot of counterpoise and there can also be a lot of problems to overcome. If you need more room consider zig zaging your wire just keep your turns at 90 degrees or more. Dipole lengths 1 2 wave antenna 468 feet freq mhz. A coaxial cable trap dipole antenna installed in the attic provides a surprisingly effective solution to hf operation on the 10 15 20 30 40 and 80 meter amateur bands at a qth with restrictive covenants that prohibit outside.

For the most common type of antenna the dipole the high voltage point is the ends of the antenna. If so a simple center fed dipole that is the size of a g5rv jr can easily work 40 through 6m and work them well with a balanced tuner at the radio.
