ARRL Field Day 2016 With Chameleon Antennas. Post #1084.

The ARRL 2017 Field Day is set for Saturday and Sunday, 24-25 June 2017. Thousands of radio amateur from Canada and the United States will be trying to make contacts world wide in one of the largest emergency communications exercises of the year.

All kinds of antennas will be used to "heat the ether" this year, ranging from simple dipoles and verticals to multi-element arrays and unconventional radiators such as magnetic and full-wave loops.

If you're in an experimental frame of mind, you may want to use a magnetic loop antenna as portrayed in this short video by Craig ("VideosByDPF").  Craig used the Chameleon Hybrid Mini and the P-Loop magnetic loop antennas with his ICOM-7200 transceiver.  Despite the rather poor conditions in June of 2016, Craig did get some interesting contacts.  Perhaps a homemade loop of your own design will be the antenna of choice for this June.  In any case, have fun and experiment a little with antennas.  You may be surprised how well magnetic loop antennas work.

Chameleon F-LOOP. Post #1083.

An exceptionally made and clearly explained tutorial from Julian (OH8STN) on how to install and use a remotely controlled  Chameleon F-LOOP magnetic loop antenna in deed-restricted housing.  In this video, Julian successfully installs this popular magnetic loop antenna in a garage and in a loft (attic).  Julian made this video for a radio amateur in Ukraine who wanted a small, stealthy antenna for his home.  Julian says the coverage from this compromised antenna is surprisingly good given its size.  A magnetic loop can also be used for portable and emergency use.

Ham Radio - D loop directional half loop transmitting antenna. (experim...


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=e6vBna3bhfU. This is post #1082 in a continuing series on "Simple Ham Radio Antennas."

For those of you interesting in experimental antenna designs, you may want to build Kevin Loughin's D loop directional half magnetic loop transmitting antenna.  Kevin says he got the idea for this unusual antenna from his research into NVIS (near vertical incident skywave) antenna systems used by the military. Kevin decided to rotate the design vertically and "make a directional magnetic loop."  Kevin says the antenna works "surprisingly well."  The antenna resembles the once popular DDDR antenna described in older editions of the "ARRL Antenna Book."

WB3GCK's Field Day Antenna Inverted L (80M-10M). Post #1081.

WB3GCK's Field Day Antenna Inverted L (80M-10M)

Here's another great ARRL Field Day antenna that is simple, portable, and inexpensive.  This easily-made inverted L from Craig (WB3 GCK) will get you on the air quickly with a decent signal covering the 80 meter through 10 meter Amateur Radio bands.

Constructing this classic antenna is fairly easy, with most materials available at the nearest hardware or building supply store.  In this case, Craig's antenna uses a 26-foot/7.826 meter Jackite pole to support the vertical section of the antenna, while a convenient tree limb supports the 27-foot/8.231 meter horizontal element.  Craig uses four ground radials, 2 measuring 16-feet/4.878 meters and 2 measuring 32-feet/9.756 meters.  A 4:1 UNUN and an antenna transmatch (i.e. "tuner") is then connected to approximately 15-feet/4.573 meters of RG-8X coax feed line.  Craig says this portable antenna works well and gets many contacts.

Don't forget to join your fellow radio amateurs on ARRL Field Day, 24-25 June 2017.

The Alpha Multiband Antenna At Field Day 2016 Winter Springs Florida 6-2...


If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=su5moLwSn0A. This is post #1081 in a continuing series on "Simple Ham Radio Antennas."

The ARRL Field Day is coming, with the event set for Saturday and Sunday, 24-25 June 2017.  Over the next few weeks, I'll be showing some videos from the 2016 Field Day contest, with the emphasis placed on new or interesting antennas used in this emergency communications event.

In this video from "videosbymike", we see the popular Alpha Multiband Antenna used with its heavy duty tripod base.  Although propagation wasn't favorable last year, some interesting contacts were made.  Hopefully this video and the ones to follow in the coming weeks will inspire you to create a Field Day antenna that will perform well for your portable operation.
