The better your antenna the more success you will have making contacts.
Attic hf antenna design.
The infamous attic dipole.
The people behind tree new bee tnb wa2608 claim that this attic mounted antenna boasts a 150 mile range.
One quarter 1 4 wave is the minimum height above ground for effective performance.
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.
And the model will generally work out for you as a good design tool.
It s a good idea to have your antenna at least one half 1 2 wavelength of the antenna.
Build an hf ham radio dipole antenna it is easy to build construct and erect a dipole antenna for the hf bands.
Mac af4ps fp 51 note.
Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield.
My 1 advice to guys working on attic antennas is to view the project as an iterative experiment.
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.
Coax shield picking up interference the coax shield when not terminated at each end acts as an independent antenna.
160 80 40 20 15 10 metres etc using a few simple components at a minimal cost and get great results.
The second problem to solve.
We have been able to neither confirm or deny it.
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.
It can potentially capture and contaminate the valid rf energy coming in from your attic shortwave antenna with undesirable electromagnetic and electrostatic interference.
And space your antennas away from the structure where possible.
