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. Like the attic dipole likely something i would do since the wife would shoot down the tower idea. Coaxial cable or coax os the most common form of feeder. So need to get licensed.

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.

The so called ocf windom is also a misnomer for the same reasons. When there is insufficient area to mount a full size dipole. The normal windom is described as having a 1 3 length leg and a 2 3 length leg. Even in what may be.

Feeding the dipole at that point yields a minimum free space impedance of 70 72 ohms. Worked europe africa middle east no problem 59 with 100w. 1 response to hidden attic dipole antenna installation. Radio antennas that are located externally are subject to the rigours of the weather.

A half wave dipole is usually fed at its center because this is where maximum current occurs. Bracketts from the previous antenna which broke still on the chimney. 2m j pole in attic. 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.

Protection from the elements. 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. I ve had a fan dipole in the attic for 17 and 20 for years. You can a 50 linear loading line in each leg of the dipole without loss.

Well after a bit of reasearch i came up with the idea of using the ocf dipole 7 band 300 watts in a loop. I have antenna restrictions ccr s say none but used some blackmail. Mac af4ps fp 51 note.
