It s a good idea to have your antenna at least one half 1 2 wavelength of the antenna.
Attic hf antenna design.
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.
Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield.
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.
The people behind tree new bee tnb wa2608 claim that this attic mounted antenna boasts a 150 mile range.
The better your antenna the more success you will have making contacts.
It can potentially capture and contaminate the valid rf energy coming in from your attic shortwave antenna with undesirable electromagnetic and electrostatic interference.
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.
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.
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.
Coax shield picking up interference the coax shield when not terminated at each end acts as an independent antenna.
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.
The infamous attic dipole.
The second problem to solve.
My 1 advice to guys working on attic antennas is to view the project as an iterative experiment.
One quarter 1 4 wave is the minimum height above ground for effective performance.
Model what you can to the best you extent you can.
We have been able to neither confirm or deny it.
