I made my own antenna like Mike's from the Radio Shack parts he
indicated. Simply used a 4-40 cap screw self-threaded into the mono
jack.
I have played with the unit for the past several weeks at the Ft Wayne
OVSS contest, our two SOAR club fields, out and around my home (no
flying fields
Another product that doesn't believe in center positive or signal and
outside negative or ground. When I made my temporary antenna for the
Frequency Checker, I assumed that the plug was wired according to the over
50 year old standard and connected it to the center. No matter, it still

At the JR Aerotow I compared mine to two of the big expensive units. I
plugged my FRS earbud into the antenna jack. Results were impressive.
Every freq the expensive units showed as active, my little Hobbico unit
showed as well.
My (two) antenna should be here soon. Maybe there is a
My Frequency Checker has a range of at least 1000 feet with a 21 inch
antenna. It was tested at our sailplane contest last month. Range could
have been more but that was as far as I could go on the mowed tow path. I
wasn't about to wade through the waist high weeds filled with poison ivy,
It looks like the Hobbico antenna utilizes a stereo plug (2 conductors +
grd).
While Mike's uses a mono plug (1 conductor + grd).
Seems to me fairly odd that Hobbico chose the stereo plug for this
application. I'd be interested to know why.

Inside the frequency checker there are two boards. One is a large LED dot
matrix display that includes the antenna jack on one
Nicely done Mike. Thanks!

Okay guys, I did some test tonite with one other verifying with his
unit. I got the official External Antenna today (two actually).
What I found is that it does virtually nothing for range. At 50' to
100' the range was not improved by installing the antenna. The unit is
still very much line

How long is the Hobbico antenna? Tower Hobbies doesn't say.
My 28-inch homemade antenna makes a definite difference, and it really
doesn't look very different from the one in the Tower
Well that sounds pretty useless to me. I don't need a frequency
checker to know what frequency I'm on. I need it to reduce the chances
that some idiot doesn't shoot me down.
I think you need at least 1000' range for it to be worthwhile.
