Yes in the attic.
Ham antenna receiver attic.
Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield.
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.
Lots of amateurs in these situations are doing so successfully especially on hf.
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.
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.
On vhf a beam antenna can work well in the attic even a rotator can be used.
Need lots of room keep them away from metal objects like heaters and ducts wire antennas can be run near the peak of the roof inside the attic bent in odd shapes to match the space available.
This is great for the amateur radio operator that is providing net control activities during a skywarn severe weather activation.
Many hams including many of you reading this are limited by hoa or other outdoor antenna restrictions.
A coaxial cable trap dipole antenna installed in the attic provides a surprisingly effective solution to hf operation on the 10 15 20 30 40 and 80 meter amateur bands at a qth with restrictive covenants that prohibit outside antennas.
It is theoretically possible to create a fire in the attic from your ham radio antenna but the conditions required for that to work require purpose and luck making this not a realistic concern for the typical attic farmer.
The mfj 931 could potentially be used a tuned counterpoise for your attic shortwave antenna.
Falling through the roof is a much more likely scenario.
Again stay away from metal and wires to maintain your pattern.
Viewer request to try out an antenna for ham radio in the attic.
Thanks david for the insulators first to comment below i ll send you.
