Mounting Ocf Dipole In Attic

In other words an 80 meter windom 137 feet long would have one leg 45 667 feet long and the other leg 91 333 feet long.

Mounting ocf dipole in attic.

Ocf dipole 160 6 meters balun designs ocf hybrid 4 1 1 1 balun antenna. 2m j pole in attic. The so called ocf windom is also a misnomer for the same reasons. I ve had a fan dipole in the attic for 17 and 20 for years.

When there is insufficient area to mount a full size dipole. So need to get licensed. Coaxial cable or coax os the most common form of feeder. You can build a double bazooka with the same results as a linear.

A half wave dipole is usually fed at its center because this is where maximum current occurs. Worked europe africa middle east no problem 59 with 100w. The better your antenna the more success you will have making contacts. There is a vent about a foot away and i ran the wires out of it.

Like the attic dipole likely something i would do since the wife would shoot down the tower idea. Even in what may be. Mac af4ps fp 51 note. Protection from the elements.

Leave a reply cancel reply. Feeding the dipole at that point yields a minimum free space impedance of 70 72 ohms. 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. Bracketts from the previous antenna which broke still on the chimney.

1 response to hidden attic dipole antenna installation. The modern common windom antenna is not an original single wire fed windom but rather an off center fed or ocf two wire feed dipole. When installing an antenna in the roof space or attic it is possibly much easier dependent upon the actual layout to route feeders into the attic. Ridgeline ocf dipole layout physically shortened dipoles are practical too for an attic antenna.

That is the way to go indoor as much wire as you can and a smartuner. I hung the balun on a beam in the attic. Radio antennas that are located externally are subject to the rigours of the weather. Required fields are marked.

Using a ladder and a strap stapler i ran the wires to the edge of the roof and then in as large of a pattern as possible. The normal windom is described as having a 1 3 length leg and a 2 3 length leg. You can a 50 linear loading line in each leg of the dipole without loss. Your email address will not be published.
