6 METER MOXON ANTENNA

This is a 2-el Yagi made from dipoles bent in the shape of a U, the longer element is the reflector, the input Z is 50 ohms and no matching network is needed.



Gain is about 6 dB, FB about 25-30 dB.

Resonant Frequency = 51.088, SWR = 1:1 measured with MFJ 269 Analyzer.

SWR is under 1.6 from 50.000 to 54.000 MHz.

Driven Element is 80in end to end with 1/2in space at feed point. The driven element also has a 10 1/4in elbow on both ends.

Reflector Element is 80 1/2in end to end, with 15 3/8in elbow on each end.

Width of antenna is 29 3/4in. Spacing between Driven element and Reflector element elbows is 4 1/8in. Make the SWR measurements by moving the reflector close to the driven element or away from driven element.

This was a fun project, coming from a Lawn Chair to an Antenna that works great, it has been tested and works great. Refer to website www.moxonantennaproject.com/design.htm

2 METER MOXON ANTENNA

MOXON ANTENNA: Invented by Les Moxon G6XN (SK 2004), is sort of a two element yagi with the elements folded and spaced to eliminate the need for an impedance match.
A carefully optimized and constructed moxon can easily exceed the gain and bandwidth of a sloppily designed and constructed yagi. Also, the moxon is smaller than the typical yagi and much smaller than the typical J-pole antenna.
The Gain is typically 7-14 dBi, depending on accuracy of construction. Although this is a directional high gain antenna, it has a very large aperture with a high front to back ratio. If pointed directly up, this can make a decent satellite antenna.




Lawn Chair parts for the antenna.
Corners from lawn chair with wood separators, one screw is good to hold it together.
Almost an antenna.



Make both sides the same, connect the coax and have some fun




THIS ANTENNA WORKED BETTER THAN EXPECTED, Had fun making this antenna, the Moxon Calculator can be found on line, making measurements easy.

HAVE FUN AT THE NEXT QSY MEETING. WA2WMJ JB

First Field Day Experience

Here's a very nice eHam.net article from Eric N2RRA. JB invited him to take part in Field Day with QSY at Bowdoin Park - Eric had never done FD and didn't know any QSY members, but brought a complete station, 3 element beam, and a boatload of enthusiasm and competitiveness to help make it a great event. Thanks Eric and come back often!

QSY Society activates Esopus Meadows Lighthouse during National Lighthouse-Lightship Week, on August 9, 2008

We primarily operated an Icom 746, using an ocf dipole for 10-80 meters, set up by JB and Fred. No pileups but we had fun nevertheless.
It was a beautiful day with cool breezes off the river, and we all had a great time, whether we operated or not.
A special thank you to Scenic Hudson for suggesting their park, to the Clearwater for allowing us use of the porch, facilities and electric, and to Save Esopus Lighthouse Commission for their ongoing work on restoring the lighthouse.

QSY Member is part of the Project Blue Horizon record-breaking team

A team of 'early career engineers' at Lockheed Martin who are also pursuing graduate degrees at Cornell University has broken the world amateur high altitude balloon record in a "near space" flight that exceeded 125,000 feet.

QSY's John Ceccherelli N2XE emailed me: Yep, I'm the advisor/mentor/subcontractor for the project. We broke the altitude record and next year we're shooting to cross the atlantic.

We flew some flights with HF and I made the students use CW (we used my DSW-20 and a MFJ morse decoder for command and control)

I want to make a meeting and tell you all about it if my schedule will ever ease up.

QSY Society Field Day 2008 Pictures

Here's a link to the QSY Field Day 2008 web album. I tried to put them in chronological order, if you have any photos, send them to me at n2skp@arrl.net and I'll try to include them as well.
Thank goodness Bob N2YYI and JB WA2WMJ shared their photos with me, or else you'd be seeing a lot less radio / antenna shots! Also thanks to the Poughkeepsie Journal for their photos, too.
