How to build a simple 2 meter quarter wave antenna.


I’m still in the process of replacing several amateur radio antennas blown apart by the passing of Tropical Storm Iselle, which did heavy damage to many homes in the Puna District of Hawaii Island.  Fortunately, the home being restored by my xyl and me wasn’t damaged, but most of my wire antennas were tossed asunder.  I’ve replaced a few of my HF wire antennas, and am now working on a few simple projects until I can get more wire from Home Depot.  One thing I did lack was a decent antenna for my old Kenwood TS-2500 HT.  I found this helpful video from K7AGE, which gave me a few helpful ideas on improving the limited range rubber duck that came with the HT.  The project is simple, inexpensive, and easy to make.  Enjoy!

Ham radio equipment for base and mobile operation

Don’t let the lack of a tower or an expensive transceiver stop you from enjoying amateur radio.  Even a simple rig and a basic antenna can do wonders for your station if they’r e installed carefully. In Tom Fuzzard’s essay, he describes the very simple station  he has assembled:  a Kenwood 820 HF transceiver, basic power supply, a power/swr meter, a telegraph key, and a Butternut 6V vertical connected to about 80 radials.  His 2 meter mobile activity is conducted through a Radio Shack HTX-252 transceiver connected to a 5/8 wavelength mag mount antenna.  With this arrangement, Tom says he works ” a number of HF bands without expending a lot of money or disrupting the natural beauty around our cabin.”  Keep it simple and have a lot of fun for very little money.  Aloha de Russ (KH6JRM).

Steve Weiss (N3ATS) has opened a new web store specializing in “all coax-fed antennas.”  On this post, Steve features a 4-band antenna, “which is only 42 feet (12.80 meters) long, yet is resonant on 30, 20, 15, and 10 meters if hung at 30 feet (9.14 meters).  For more information, visit http://n3ats.com.  Aloha de Russ (KH6JRM).

The long fight to erect antenna “support” structures has come to a favorable end for amateur radio operators in Poway, California.  Following a decision to allow antenna support structures up to 65-feet/19.81 meters, Poway city councilmembers denied a request from neighbors to reconsider their ruling.  Councilmembers rejected the appeals.  Aloha de Russ (KH6JRM).

Simple Ham Radio Antennas: The Multiband HF Stealth Vertical.

http://www.tonymilluzzi.com/2013/10/my-multiband-wire-vertical-antenna.html.

I ran across this article by Tony Milluzzi (KD8RTT) while I was searching for some stealth antenna ideas for my “antenna farm” at my new QTH in the Puna District of Hawaii Island.  Most of my wire antennas were “rearranged” by Tropical Storm Iselle on 07-08 August 2014.  Although the house survived intact, the antennas strung between several trees “bit the dust.”  So, I’m rebuilding the antenna site with wire recovered from the storm. What Tony has to offer is an excellent way to rig a 40, 20, and 10 meter stealth vertical using a sturdy tree as the antenna support.  With 16 buried radials and suitable 50 ohm coax, which is also buried, Tony has an antenna that can’t be seen in his HOA-restricted housing area.  He found this stealth antenna performed much better than the antenna mounted in his attic.  When I was fist licensed as a novice operator in 1977, one of my first antennas was exactly like this, the only exception being the coconut tree serving as the “mast.”  Like Tony, I was surprised just how well the antenna worked.  I used this arrangement for several months until I acquired a used Drake MN-4 antenna transmatch to smooth out the small amount of SWR found in my system.  I still have the old Drake MN-4.  A suitable Norfolk Pine Tree is located about 60 feet/18.29 meters from the shack. It appears Tony’s antenna will be resurrected near a rainforest in the Puna District.  I’ll keep you posted.  Aloha de Russ (KH6JRM).

NVIS Loop Antenna Made Simple.


http://www.youtube.com/playlist?list=PL58E9802D88B44EI.

I found this 3-part video while I was searching for NVIS (near vertical incident skywave) antenna ideas.  The videos are part of the 2011 IDEX Military Show at the Stealth Telecom booth.  The antenna is a tunable magnetic loop that can be mounted on a vehicle roof.  Stealth Telecom designed this NVIS antenna for the military.  The claimed range is between 300 to 500 miles.  Although no price was given, it could be quite expensive, given the requirements spelled out by the military.  It would be nice to have one of these antennas for emergency use.  Oh, well, it’s back to low-elevation dipoles and full-wavelength loops for my new NVIS antenna.  Aloha de Russ (KH6JRM).

Ham Radio 40/80/160 Meter Inverted V Dipole Antenna.


Excellent, easy to follow tutorial from Dave Tadlock. (http://www.youtube.com/watch?v=GLhNUmolKKY).

Now that I finally have a decent backyard at my new QTH, I think I’ll try this simple coil loaded inverted v dipole antenna…160 meters has always eluded me because of space limitations.  It’s time to unpack the soldering gun and get this antenna in the air.  Nice video.  Aloha de Russ (KH6JRM).
