Dipole and long wire antennas can also be used with mobile outdoor style auto tuners feeding them in an attic space.
Attic hf ham antenna.
The radio antenna that can receive and transmit the signals between 3 30 mhz are known as the hf antenna.
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.
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.
Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom.
Falling through the roof is a much more likely scenario.
They are very useful in radio communication or even the tv signal reception.
Using the cq antennas center insulators from ke5fen.
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.
As with most antennas the more height the better for indoor operating however most hams recommend using low output power.
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.
The same techniques apply.
The same dipoles and loops that you use in your attic can also be used in any other room in your home.
Hf in the hf antenna stands for the high frequency.
On vhf a beam antenna can work well in the attic even a rotator can be used.
Bare copper antenna wire stapled directly on wood rafters causes loss of rf signal energy.
With his antenna matching unit providing an acceptable match he s on the air making contacts.
With time bare copper oxidizes the wood where the wire is tightly stapled to absorbs some of this oxidization and forms a loose yet lossy bond with the wire.
Viewer request to try out an antenna for ham radio in the attic.
This is great for the amateur radio operator that is providing net control activities during a skywarn severe weather activation.
Thanks david for the insulators first to comment below i ll send you an insulator in the mail.
Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield.
Again stay away from metal and wires to maintain your pattern.
