HF Antennas Especially stealth models for those in an HOA. Post #1540. http://www.bvarc.org/pdf/HF_Antenna_by_KD5FX.pdf. Accessed on 30 June 2018, 1943 UTC, Post #1540. Author:  Dave Land (KD5FX). Please click link to read the full article. Comment: Erecting a high-performance antenna in a deed-restricted property (HOA/CC&R) can present some difficult challenges for radio amateurs.  Dave Land  (KD5FX) explores this issue in depth and comes up with several antenna designs that could be used in such areas.  Each antenna is fully described with both drawings and photos, so you can easily build each design quickly and efficiently.  Overall, Dave has done an excellent job of assembling antennas that can be used in limited spaces. Here are the major antennas described in Dave's article: The basic dipole, multiband dipoles, random length multiband antennas, verticals, flag pole verticals, inverted V, mobile antennas adapted for backyard use, the fencetenna, G5RV, W5GI

An amateur radio 2 meter/70 cm antenna made from an old coffee can. Post #1539.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=c2AyfBMRztw. Common household objects can often be used as antenna elements.  Such is the case with this excellent video tutorial from Dave Tadlock (KG0ZZ).  Dave shows how an old coffee can can be repurposed as a home made 2 meter/70 cm antenna.  All you need is a vertical element cut to the correct length and some kind of metal ground plane or counterpoise to complete the antenna.  The shield of your coaxial feed line might serve this purpose.  A clearly explained, step-by-step procedure that will have you on the air with a fully functional 2 meter/70 cm antenna in a short time.  Depending on what you have in your ham shack, this project could cost you very little.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=gWIsU1Sy3NY. HF Delta Loop Antennas are quiet, versatile, and cost effective antennas for radio amateurs who have room for only one HF antenna.  In this video, "DENMONKEY" takes us step-by-step through the design, construction, set up, running support ropes, and raising of the antenna.  In this case, the antenna is fed at the apex of the support mast using a 4:1 balun connected to convenient length of 50 ohm coaxial cable.  Six to eight turns of the coaxial feed line serve as an RF choke.  In this configuration, the Delta Loop is vertically polarized.  Multiband operation is possible by using a balanced feed line into a balanced antenna "tuner" or into a current balun, coax, antenna "tuner" combination. In Part 2, DENMONKEY tests the antenna and makes a few adjustments. For the latest Amateur/Ham Radio news and information, p

How a simple counterpoise system can lower your SWR. Post #1534.

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=SwhlSa8CUCk . Every vertical antenna needs a ground radial or a counterpoise system to realize maximum efficiency and reduced SWR.  If you can't lay in a ground radial system, then a counterpoise system consisting of 1/4 wave length wires running parallel to the ground, suspended over the ground under the vertical antenna will insure that SWR is tamed and that your vertical antenna is radiating more efficiently.  In this video, the antenna in question is a tri-band 6 meter, 2 meter, and 70 cm vertical with added counterpoise wires.  An interesting project that you can complete in just a few hours.

Please click link to read the full article and related topics. Comment: I've always favored "homebrewed" wire antennas for the annual ARRL Field Day, which occurs on the third full weekend of June.  Whether I've opted to run my portable station in my backyard (because of work requirements) or chosen to help with the Big Island Amateur Radio Club Field Day site, I always have a spare DIY antenna in my van or under my operating desk.  Along with my portable multiband HF antenna, I also carry a "go-kit" with a HF transceiver, solar panels, deep cycle marine battery, an antenna "tuner", spare feed lines (usually 450 ohm ladder line), and a variety of 1:4 and 1:1 current baluns.  I've tried a few of the antennas described in this article and found them to be reasonably simple, portable, and

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=jEO9JSRXeZI. One of the joys of Amateur/Ham Radio is the ability to experiment with antennas and various pieces of equipment.  We can learn a lot about our hobby by just getting down to "the nuts and bolts" of designing, building, and testing our homemade accessories and repairing our equipment.  This is particularly true of antennas, where unconventional designs often work very well. In this video, Kevin Loughin (KB9RLW) continues his series on magnetic loop antennas by showing and testing some of his designs built on his workbench.  Most of Kevin's projects use locally available materials from neighboring home improvement and hardware stores.  If you're in an experimental mood, why not try some of Kevin's magnetic loop antenna designs?  These simple projects should be of particular interest to those operating in deed-restricted prope

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=nnN0NVGqtKQ. Those of us who use vertical antennas for our ham radio stations know the importance of having a good ground radial system.  Ground radials supply "the missing half" of our quarter wavelength vertical antennas and make those antennas more efficient. Installing ground radials can be quite a task, especially if you want more than the bare minimum ground radial system.  In this video, Rich Rodgers uses an electric edger to dig  fairly straight groves to lay his radial wires.  You may want to keep the wires flat with plastic lawn staples available at many hardware stores.  This seems to be a good way to install ground radials.

Inverted V Dipole Antennas are simple, inexpensive, portable, and capable of multiband operations using a variety of options.  In this video, Dave Tadlock (KG0ZZ) uses homebrew coils to convert his inverted V antenna into a dual-band, 40/80 meter antenna.  The video offers valuable suggestions on adjusting the loading coils for optimum efficiency on both 40 and 80 meters.  This coil-loaded 40/80 meter inverted V would make an excellent HF antenna for the upcoming ARRL Field Day, especially now that propagation is favoring 160, 80, and 40 meters.
