The infamous attic dipole.
Attic dipole antenna.
For the most common type of antenna the dipole the high voltage point is the ends of the antenna.
The rf losses are fairly low in wood and most roofing at hf vhf most of problem comes from interaction with electrical wiring and ductwork.
Mac af4ps fp 51 note.
Attic antennas can work better than you might think some of mine work as well as their outside counterparts no i m not comparing to a 150ft tower big yagis.
The better your antenna the more success you will have making contacts.
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.
Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.
With his antenna matching unit providing an acceptable match he s on the air making contacts.
