HF Antennas. Especially stealth models for those in an HOA. By Dave Land. KD5FX Single band antenna when fed by coax. Works good for multi-bands when Hamstick dipoles. Isolate one for each band. 80 mtr pair. Could be any band. Must be in pairs. Best to tune-up on a vehicle. Could be mounted in attic. Or in back. Attic antennas can work better than you might think, some of mine work as well as their outside counterparts (no I'm not comparing to a ft tower & big yagis). The RF losses are fairly low in wood and most roofing at HF & VHF, most of problem comes from interaction with electrical wiring and ductwork. This creates.
When we purchased our first home in amateur radio antenna siting was a top selection criteria. But when a As attics go, I consider ours is very amenable to the presence of an amateur HF antenna. After consideration of the alternatives, I chose to construct a trap dipole antenna in my attic using coaxial-cable traps. Since I was visited by the local planning officer (a force to be reckoned with) I am pretty much limited to an out-side doublet for H.F. and loft aerials for all higher bands. Not a completely . Indoor/Attic/Stealth antennas are a lot of fun and I think they do add something else to your enjoyment of ham radio.A Well Behaved Multi-Band Attic Aerial.
