The infamous attic dipole.
Ocf dipole 160 6 meters balun designs ocf hybrid 4 1 1 1 balun antenna.
Coaxial cable or coax os the most common form of feeder.
Mac af4ps fp 51 note.
Required fields are marked.
The so called ocf windom is also a misnomer for the same reasons.
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 normal windom is described as having a 1 3 length leg and a 2 3 length leg.
I have antenna restrictions ccr s say none but used some blackmail.
A half wave dipole is usually fed at its center because this is where maximum current occurs.
Radio antennas that are located externally are subject to the rigours of the weather.
Bracketts from the previous antenna which broke still on the chimney.
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.
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.
Like the attic dipole likely something i would do since the wife would shoot down the tower idea.
Coax hookup for vertical uhf vhf vertical antenna at the base of the chimney.
Replaced with a smartuner auto coupler and dipole configuration and get all bands.
That is the way to go indoor as much wire as you can and a smartuner.
Well after a bit of reasearch i came up with the idea of using the ocf dipole 7 band 300 watts in a loop.
Even in what may be.
Ridgeline ocf dipole layout physically shortened dipoles are practical too for an attic antenna.
You can a 50 linear loading line in each leg of the dipole without loss.
The better your antenna the more success you will have making contacts.
I hung the balun on a beam in the attic.
I ve had a fan dipole in the attic for 17 and 20 for years.
So need to get licensed.
You can build a double bazooka with the same results as a linear.
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.
1 response to hidden attic dipole antenna installation.
Worked europe africa middle east no problem 59 with 100w.
When there is insufficient area to mount a full size dipole.
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.
