A Quick, Simple, Inexpensive Trailer Hitch Antenna Mast. Post #1050.

A Quick, Simple, Inexpensive Trailer Hitch Antenna Mast (http://www.eham.net/articles/38039). Accessed on 21 February 2017, 21:35 hrs, UTC. Author:  Joe Tomasone (AB2M). Please click link or insert title URL into your browser search box to read the complete article. Comment: A nice, well-written, and richly photographed tutorial on building a sturdy, inexpensive trailer hitch antenna mast.  Just follow the suggestions outlined in this article and you should have little trouble attaching the hitch to your vehicle and supporting a lightweight antenna for portable operations. In the comment section of the article, KE4ZHH suggests using a telescoping fiberglass mast with the trailer hitch.  One could easily use the tip of the fiberglass mast to support an inverted vee antenna.  Either way, this article is a good example of what can be done with simple materials.

No Tuner "Shorty" HF-Band Antenna. Post #1049.

No Tuner "Shorty" HF-Band Antenna (http://www.w5dxp.com/notuner/shorty.fig). Accessed on 20 February 2017, 20:15 hrs, UTC. Author:  W5DXP. Please click link or insert title URL into your browser search box to read the article. Comment: I found this article by W5DXP while I was looking for an easy, inexpensive, and portable HF multiband antenna for my home-in-progress in Hawaii Island's Puna District.  Clearing an acre of land is a slow, tedious process, but, taking a break for some amateur radio contacts, reinvigorates my spirits.  I wanted an antenna that could be erected quickly between two Norfolk Pine trees in my back yard. The design from W5DXP is self-explanatory with all of the details necessary to build this simple, effective antenna.  If you build this antenna according to the illustration from W5DXP, you should have good results.  Best of all, there is no antenna transmatch (i.e. "tuner") involved.

40/20/10 Meter Fan Dipole Antenna (http://www.worldwidedx.com/threads/40-20-10-meter-fan-dipole-attic-antenna.178104/). Author:  KD2GOE. Accessed on 20 February 2017, 00:35 hrs, UTC . Please click link or insert title URL into your browser search box to read the full article. Comment: If you have a large enough attic in your deed-controlled home, you may find this variant of the fan dipole just what you need to get on the air and enjoy the challenge of amateur radio. KD2GOE does an excellent job of explaining how he built this effective, inexpensive stealth antenna that covers the 40, 20, and 10 meter bands. With a little help from an antenna transmatch (i.e. "tuner"), this antenna will work fairly well on 12 and 17 meters.  The photographs are excellent and give you an excellent illustration of what can be done in a limited space.

Coil-shortened dipole antenna calculator. Post #1047.

Coil-shortened dipole antenna calculator (http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=32516). Author:  J.J. Johnson Accessed on 18 February 2017, 19:50 hrs, UTC. Please click link or insert title URL into your browser search box to read the full article. Comment: Here's another useful tool for antenna experimenters. With the suggestions given in this article, you can design, build, and use an effective dipole antenna that needs much less space than a full-sized dipole by adding two simple, inexpensive loading coils. The article provides a simple set of formulas to help you through the design and building process.  The author also supplies a simple coil inductance calculator and a link to a related article by Jerry Hall (K1PLP) in the September 1974 issue of "QST".

If you can't view this video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=4CQ3WDcfYBU.  Here's another creative idea for an antenna in a deed-restricted home.  Apparently, the beautiful bird house at the top of Rich Rogers's mast is permitted, so he modified his 53 foot/16.158 meters Ultimax DXtreme End Fed Antenna to fit the limitations of his property. Rich says he's able to return to the air with no one suspecting that the bird house (which is actually used by birds on his lot) is disguising his HF amateur radio antenna.
