Attic Hf Antenna Design
A coaxial cable trap dipole antenna installed in the attic provides a surprisingly effective solution to hf operation on the 10 15 20 30 40 and 80 meter amateur bands at a qth with restrictive covenants that prohibit outside antennas.
Attic hf antenna design. It is easy to build construct and erect a dipole antenna for the hf bands. 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. Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier tech shield. 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.
Bare copper antenna wire stapled directly on wood rafters causes loss of rf signal energy. It s a long way from the rabbit ear designs you might think of when picturing indoor antennas and much cooler looking than the metal contraptions often found outdoors. You ll hardly be able to find a more powerful or practical model within the same price range. Dipoles are widely used on bands like 80 metres 40 metres 20 metres 15 metres and 10 metres where they can provide excellent levels of performance.
To sum it all up with its long range tree new bee tnb wa2608 is a great amplified attic antenna that comes at a really affordable price. 160 80 40 20 15 10 metres etc using a few simple components at a minimal cost and get great results.
