This picture shows the base of the antenna, the rest of it above is just a plain old boring length of aluminum tube ;)
I have a multiband dipole which works well on 10M but feeling that there was room for improvement and being a fan of verticals, I splurged and put up a 10M Ringo Ranger.
The Ringo Ranger designs have been around for a long time with basic Ringo being a design by W1BX. This antenna design is available for 10, 6, 2, and 440 HAM bands and also commerical bands and was also used below 10M for CB and other uses.
The 10M Ringo Ranger is basically a half wave end fed antenna where the circular ring is an inductor and a coax tuning stub is a capacitor which provide the matching circuit for the feedline to the antenna.
For some time I have been putting a 1:1 choke balun at the feedpoint of my antennas as well as in the shack. These are relatively simple and inexpensive to make and this time rather than winding parallel wires around a ferrite core I decided to try coax. In this case I used RG-142 of 10 turns around a dual FT240-31 core wrapped with glass fiber tape and with type N connectors on either end. The type N connectors are crimp on style and all together made for a simple easy to make and assemble choke balun. This was all mounted in a Carlon 4x4x2 junction box. This in turn was mounted to an aluminum plate which in turn was attached to the supporting pipe with U bolts. the picture below was taken just before I tidied up the windings a bit more and screwed the cover on.
The ferrite cores where purchased from "the Toroid King" W8DIZ through is online shop: Kits and Parts
I still haven't figured out a good way to use the SWR analyzer for testing common mode rejection yet, but I am still experimenting.
Every good antenna installation requires good attention to detail. For every antenna project I put together I religiously use stainless steel hardware and a product called Penetrox (do a search, you will find many links) and good practice for sealing all feedline connections.
Penetrox is described as fine zinc particles in a petroleum base and is used to prevent oxidation of metal to metal connections and joints. Use it on the antenna's tube to tube joints and electrical connections. Many use a silicone grease in an attempt to waterproof PL-259 connections but instead I use just a wee dab on the threads to prevent seizing.
For sealing PL-259/SO-239 or Type N or whatever feedline connections I used to use a product similar to Coax-Seal. Coax-Seal is a self amalgamating rubber tape that when stretched and wrapped around your connector and coax would provide a good weather and water proof seal. The finishing touch was to wrap the outside with black electricians tape - bottom up - so as to provide a path for water to run off.
I used that technique for many years but just recently have switched to 4:1 shrink double wall with adhesive 3/4" heat shrink tubing. A 3" length will cover any connection and once shrunk into place will provide a weather and waterproof cover as good or better than anything else. The 3/4" is a tight slip over type N fittings but easily fits over PL-259's and will shrink just right for RG-8X (mini RG-8) cable.
