10 meter dipole in attic.
This was found to be quieter and made the antenna less sensitive to frequency changes.
To 10 meters one band at a time larger versions will work on 80 or 40 mtrs how to website.
The ocf dipole is like a standard horizontal dipole but fed at a position other than the center typically at the 1 3 2 3 position.
I went to my friends house to check out his setup and get him up and running on some hf digital modes.
All i did was make spacers out of 1 2 pvc tubing the wire is spaced 6 off center.
Dipole easy and cheap to build can be made with small gauge wire.
In my opinion it s a work of art.
To fit this antenna in an attic space i used an inverted v configuration.
Mac af4ps fp 51 note.
This is my attic 40 20 10 meter fan dipole that i installed in my attic today.
This was okay but appeared noisy.
I later changed this by feeding the dipole twin feeder via a remote balun.
I initially feed the dipole directly with a 1 1 balun and rg58 coax.
Seriously consider the ocf dipole to find an impedance on a 68 foot antenna that can provide a reasonably good match across multiple bands which are even harmonically related such as 80 40 20 10 and 6m.
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.
Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier.
