A second advantage to mounting the antenna in the attic is that you will be protected from lightning strikes in the event of severe weather.
Ham antenna in attic.
Lots of amateurs in these situations are doing so successfully especially on hf.
Using the cq antennas center insulators from ke5fen.
The house will act as a natural shield and as long as your attic mounted antenna system is independent to the rest of your antennas lightning won t be an issue.
On hf wire beams can be run on the roof supports or the rafters these usually are good for one direction only but can be switched electrically for different coverage.
Many hams including many of you reading this are limited by hoa or other outdoor antenna restrictions.
Yes in the attic.
But even if you can t put up an outdoor antenna you can still operate with antennas installed in an accessible attic space.
Even if it is mostly used by ham radio operators to solve problems while transmitting the mfj 931 should also work for a receive only purpose.
Thanks david for the insulators first to comment below i ll send you an insulator in the mail.
The mfj 931 could potentially be used a tuned counterpoise for your attic shortwave antenna.
On vhf a beam antenna can work well in the attic even a rotator can be used.
