Mounting ocf dipole in attic.
I ve had a fan dipole in the attic for 17 and 20 for years.
Feeding the dipole at that point yields a minimum free space impedance of 70 72 ohms.
I hung the balun on a beam in the attic.
Like the attic dipole likely something i would do since the wife would shoot down the tower idea.
Required fields are marked.
Ridgeline ocf dipole layout physically shortened dipoles are practical too for an attic antenna.
The better your antenna the more success you will have making contacts.
Protection from the elements.
Coaxial cable or coax os the most common form of feeder.
You can build a double bazooka with the same results as a linear.
You can a 50 linear loading line in each leg of the dipole without loss.
Radio antennas that are located externally are subject to the rigours of the weather.
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.
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.
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.
The so called ocf windom is also a misnomer for the same reasons.

Replaced with a smartuner auto coupler and dipole configuration and get all bands.
Ocf dipole 160 6 meters balun designs ocf hybrid 4 1 1 1 balun antenna.
That is the way to go indoor as much wire as you can and a smartuner.
A half wave dipole is usually fed at its center because this is where maximum current occurs.
There is a vent about a foot away and i ran the wires out of it.
Well after a bit of reasearch i came up with the idea of using the ocf dipole 7 band 300 watts in a loop.
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 modern common windom antenna is not an original single wire fed windom but rather an off center fed or ocf two wire feed dipole.

Bracketts from the previous antenna which broke still on the chimney.
So need to get licensed.
Worked europe africa middle east no problem 59 with 100w.
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.
The infamous attic dipole.
2m j pole in attic.
Coax hookup for vertical uhf vhf vertical antenna at the base of the chimney.
