Antenna Project -- Show and Talk

The November SARC meeting featured home brew antennas and there were some very interesting projects on display.
Here are a few photos taken by our club photographer Hiu Yee VE7YXG.

Wayne Galauger, VE7ZNU brought two antenna tuners, the first project
started four years ago, it was a manual antenna tuner from the Burnaby Club.
The other is an automatic tuner that can take up to 3 kilowatts, the
small one only cost $10 to make but the bigger one $2000, this one is
looking soley on SWR, all the information is stored in the micro
processor, Wayne finished with fielding questions from the group
and links to the network software websites.

Wayne is president of the Coquitlam ARC and has led the club in a number
cool electronic projects.

Wayne demonstrated his home brew 3KW automatic antenna tuner and outlined
his future plans for the tuner. Wyane has been at this project for over four years.

John Brodie, VE7SSB next showed us his home brewed manual built tuner.
The Ultimate transmatch tuner, which he built approx. 30 years ago,
it was a project from the QST magazine.
John then took questions and suggestions.

John VE7JBB showed his home brew manual tuner and talked on the assembly
over the years.

Mike Plant, VE7AT then showed his home brew antennas, one made from
three metal rulers and some PVC pipe, that is able to get 2m, 220 and 440,
he also showed us his home brew Moxon 2m vertical directional antenna.

Mike and his home brew dual band antenna. Mike explained that the parts
were acquired at Home Depot and the cost was minimal.
The performance is very good says Mike.

Mike also showed his Moxon 2 meter antenna and how simple it was to construct,
just hardware store components.

Hiu Yee, VE7YXG had a $2 J-pole that consisted of three pieces of welding rod
screwed together with no soldering involved.

Hiu and his home brew modified J-pole antenna. He outlines
the construction and performance of this 2 meter antenna.

Fred Reichstien, VE7MPI came with a similar antenna to the J-pole but with four
stops one on each corner, this is non-directional, you adjust the
match with one telescoping 3/8th rod.

Fred demonstrates his modified J-pole 2 meter omni directional gain antenna.

Gordon Kirk, VE7GRK showed us a 1/4 antenna he had for 30 years, it wrapped
with electricians tape, epoxy and coiled wire.

Gordon also showed a kit he won from California, a portable with coils,
he can work 10 to 80 meters, it uses computer ribbon wire or the radials.

Gordon demonstrates his HF antenna kit.
This antenna is compact and easy to assemble in the field.

Fred Orsetti, VE7IO with his directional tape measure beam, he bulit last year specifically
for bunny hunting, he even made a holder on the shaft of the beam to hold his radio.

Fred demonstrates the home brewed tape measure antenna used for direction
findig, the antenna assembly has a 4 Mhz offset attenuator which allows
excellent reduction of the signal when close to the target.

The meeting was very well attended and everyone seemed to enjoy the information on antennas and antenna tuners.
Anyone wishing further information should contact the presenters directly.
