Attic Hf Ham Antenna

Thanks david for the insulators first to comment below i ll send you an insulator in the mail.

Attic hf ham antenna.

Falling through the roof is a much more likely scenario. The radio antenna that can receive and transmit the signals between 3 30 mhz are known as the hf antenna. 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. 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.

Viewer request to try out an antenna for ham radio in the attic. They are very useful in radio communication or even the tv signal reception. Using the cq antennas center insulators from ke5fen. With his antenna matching unit providing an acceptable match he s on the air making contacts.

The same techniques apply. On vhf a beam antenna can work well in the attic even a rotator can be used. The attic shortwave antenna wire this is the most importantaspect to improve. Hf in the hf antenna stands for the high frequency.

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. Another local uses an hf loop antenna tacked up around the circumference of the ceiling of a second floor bedroom. 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. As with most antennas the more height the better for indoor operating however most hams recommend using low output power.

Again stay away from metal and wires to maintain your pattern. 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. Keep the antenna as high off the floor as possible. Bare copper antenna wire stapled directly on wood rafters causes loss of rf signal energy.

The same dipoles and loops that you use in your attic can also be used in any other room in your home. Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield.
