MK, this diagram is fantastic! I guess I should have explained to all
of you that as a college student I have more time than money, so it may
be a while before I can even afford the PVC and wire. I bet it will
outperform my mobile-dipole-on-a-stick, though!

hi Nelson,

yes, it is a lot of work, you could just attach the magmount
to any metal object, patio table, metal railing or window a/c unit, etc.Yea, I suppose you could... Arf.... :/



or for a few dollars and less work build a great 2m antenna
using #12 thhn wire and a few feet of pvc pipe.With even less work and $$$, he could just build a ground plane
using 5 wires and a so-239 or whatever..



this is the half square, works great, it is directional.Probably not what he wants for 2 meters, unless he can steer
the pattern.

then you can try this one, the Moxon for 2m, little harder to make
but has similar gain to a 2 element yagi in less space and direct fed
with 50 ohm coax (like the half square is fed).Antennas are small on 2m.. He could live a little and use 3 elements
and have a good bit more gain. But then he has to rotate the thing..
I recommend a easy 1/4 wave ground plane to start. It will work about
as well or better as any of the other "easy" vertical whips for 2
meters.
Attaching a 2 meter whip to a railing, table, AC unit , etc is going to
function in a fairly poor manner. The ground radials need to be
resonant to function properly. Would be much better to use 4 simple
quarter wave radials. You can slope them down at about 45 degrees
to get a better match, and maybe a tiny bit more gain.
