A friend ran a vertical antenna up the outside of his chimney and painted it to match. Don't remember what else he did, but he got reasonable results, I think.

I installed my first dipole under the eves of my uncle’s home on Long Island. It was 40 meters and worked great. I also had a 40 and 20 meter dipoles in the attic of my home in St Johns FL. They also worked great.

4:26 In that configuration, the antenna becomes a slot antenna as it is feed parallel to the radiator (look at hentenna). The Folded dipole is fed in series to radiator. I am trying to remember which particular case it is: lowest SWR or widest bandwidth.

I believe each time you add a parallel radiator on a folded dipole, the feed point impedance multiplies by 9 (or was it 7?). My ARRL Antenna manual is buried so I can’t check it.

What about putting transmission ladder line in pvc conduit for say 20 feet if the conduit is in clear space?

Don't know what rotor cable is but, #16 lamp cord is about 72 Ohms and was popular to feed a dipole in the Tube days before coax. A folded dipole is a one bander unless you load up the feedline,

A rotor cable are the cable that is between the controllbox and antenna / tower rotator. It contains multiple strands :)

The G3TPW Cobwebb antenna uses speaker wire and passes one wire through the feedline box and the other wire begins and ends at the box where both ends get tied to the coax connector. The outer ends are tied together like a folded dipole. Apparently this gets up to 7dBi gain and is omnidirectional. Few people sell these things, however, making most of them homebuilt. Been trying to import one to Japan but that's like pulling hen's teeth. Anyone have one to sell?

Thank you, Dave. I have found some strange things on the Internet. Sometimes, I experiment and find out it works, many times not. N0QFT
