Here's a handy device that will keep rf off your coaxial cable feed line. PD1AIV has done an excellent video tutorial covering the basic tools, materials, and construction practices needed in making an "ugly balun" or RF choke suitable for 8o through 10 meters. You will need around 19 to 21 feet (5.49 to 6.40 meters) of 50 ohm coaxial cable plus fittings to make the choke. PVC pipe, screws and nuts, and a few connectors will be all you need to complete this project.

Experimenting with antennas and limited spaces is fun and educational.  In this video, we see how a garden in the UK can be used to accommodate a homebrew dipole antenna.  According to "Daz", this 108-ft/32.92 meter antenna works on all bands from 80 to 10 meters "without any problems." Although coaxial cable is used as the feed line into an antenna "tuner", he concedes that ladder line would probably work better. He used an "air coil" made from 7 turns of coax at the base of the antenna. Despite the antenna's appearance and length to fit dimensions, it worked well. Don't be afraid of trying various antenna designs--that's part of the fun of Amateur Radio.

Operating Stealthy from a Condo - CQ WPX SSB 2017. Post #1215.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=MyML4xIGQ0. Nicely done video from Thomas (rcobo101)(AC2RJ), showing us how to operate HF QRP SSB temporarily from a HOA zone.  His antenna was supported on a 20 foot/6.097 meters telescoping fishing pole with a 16 foot/4.878 meters counterpoise.  His Yaesu-817 QRP HF transceiver did very well on the 20 meter band during the recent CQ WPX SSB 2017 contest.  Don't let deed-restricted properties stop your enjoyment of Amateur Radio.

Multiband HF portable antenna, the easy way. Post #1214.

Thanks to "rcobo 101" for this simple, effective, multiband HF vertical antenna. Basically, the antenna is a vertical helix wrapped with 1/2 wavelength of wire for the lowest band of operation.  The winding serves as a 1/4 wavelength vertical and can be used with a suitable ground radio/counterpoise system and antenna "tuner" for the HF band of choice.  Although multiband operation is certainly possible with an antenna "tuner", this particular design works best on the band of your choice.  In this video, "rcobo 101" used 35 feet/10.670 meters of speaker wire wrapped as a helix on a 20 foot/6.097 meters telescoping fishing pole.  As such, this antenna is ideal for the 20 meter band.  According to "rcobo 101", his antenna "tuner" allows satisfactory operation on all amateur radio bands fr

Easy Mobile Camp Setup. Post #1213.

Camping and Amateur Radio make an excellent combination.  Enjoy the beauty and solitude of the great outdoors while contacting the world with your portable "Go-Kit." Here's a nicely done video from K0PIR made during a camping trip to the Black Fox campground in the Black Hills of South Dakota...great scenery complimented by a fast flowing stream and pleasant surroundings. K0PIR's simple operating system is more than enough to get you plenty of contacts.  A simple antenna (with ground system if you're using a vertical antenna), a small antenna "tuner", a multiband HF transceiver, and a solar-powered battery should give you hours of fun and relaxation without all of the noise, traffic, and confusion of an urban setting.
