Attic Hf Antenna Design

Coax shield picking up interference the coax shield when not terminated at each end acts as an independent antenna.

Attic hf antenna design.

Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield. Dipole antennas often are the easiest to build and then turned into inverted v antennas by raising the center of the antennas up into the inverted v style. And space your antennas away from the structure where possible. The infamous attic dipole.

It s a good idea to have your antenna at least one half 1 2 wavelength of the antenna. One quarter 1 4 wave is the minimum height above ground for effective performance. The people behind tree new bee tnb wa2608 claim that this attic mounted antenna boasts a 150 mile range. But we can tell you that while its range may be a little shorter than advertised it is definitely up there somewhere in that 150 mile vicinity.

My 1 advice to guys working on attic antennas is to view the project as an iterative experiment. This antenna features a patented design that generates enough power to provide a signal to multiple televisions in one home even when located in an attic and it can support a variety of broadcast types including hdtv 1080p and even 4k ultra hd. We have been able to neither confirm or deny it. 160 80 40 20 15 10 metres etc using a few simple components at a minimal cost and get great results.

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. Model what you can to the best you extent you can. The better your antenna the more success you will have making contacts. Mac af4ps fp 51 note.

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. Build an hf ham radio dipole antenna it is easy to build construct and erect a dipole antenna for the hf bands.
