Yagi question
 

I'm looking to build a 2m yagi, but I haven't got any money. Can I
make one out of aluminum coat hangers? I also have a 4-foot section of
1" PVC pipe laying around, and glue, tools etc.

How about a 7dB 2M Yagi for $7 -- less if you have some PVC and Welding Rods

Had no problem viewing it, thanks! I'm still looking for ideas, though-
I think I'm turning out to be one of the "homebrew" hams. Would
clotheshangers even be able to handle the 50W of my radio? 5W?

You can make one out of anything nearly. Coathangers will work fine,
but most
I see are steel, not aluminum. Aluminum would be better. Steel
coathangers
will work ok, but they rust real fast. Power is no problem. Unless
there is a
weak link with the matching device, a coathanger yagi should handle
several
hundred watts. The matching device will be the trickiest part to
construct
using hangar wire and PVC. Would almost be easiest to design the yagi
to have a 50 ohm feedpoint with spacing adjustments, and feed with a
normal split
driven element. I'd add a coax choke for decoupling the feedline.

There is a set of plans on the `net for one made of an old, broken
tape measure. The pieces of the tape measure are glued / screwed to a
length of PVC, and the Coax was soldered / screwed to the drive
elements.
If you have this stuff laying around, and you sound as you do, then
this would be a free-bee for you. My friend made a three element
version, and it worked surprisingly well with about 7 dB gain. With
the flat, razor thin but wide, flat elements, the pattern was very
direct. It looked a bit funny, but hey, the darn thing works like a
champ!

Others presented good ideas. Ya know, an old TV antenna would make a decent
yagi for 2m, and with people going to cable/satellite TV, you could probably
find one for nothing or only a few dollars. Remove the elements you don't
need, cut the remaining elements down to length, do a little rewiring as
needed, connect your feedline, and you're good to go. If you want vertical
polarization, redrill the boom-to-mast mounting holes 90° from original.

I once did something similar with a 3 element 11m yagi... in about an hour
or so including tuneup time, I turned it into a gamma-matched 6 element 2m
yagi. I used my VSWR-protected 2m rig's output indicator to indicate proper
tuning by adjusting for maximum relative forward power.

When we got cable in the neighborhood my wife was threateing divorce over
all the TV antennas I would pick up off the curb during trash day.

Hmm... I envision stacked arrays! ;^)

I actually did very little with them. I didnt have my ticket yet. I put a
couple up in the attic for local TV that wasnt on cable. Still use them when
a storm takes the cable out.

Yagi question
 

Ok, here's what I tried. I cut notches in that 4' piece of PVC and cut
clotheshanger wire to the lengths found at this calculator:

http://www.csgnetwork.com/antennae3ycalc.html

This I stuck out my window on an aluminum pole (cinderblock walls are
bad). I'm suspicious of my wiring- I used very thin speaker cable to
connect a ground to the screws on my light switch plate, and to the
coax going into my radio. It doesn't perform half as well as my
current antenna- a mobile 5/8 dipole on the end of some eye-bar with
clothes-hanger groundplane radials. Guess I just need to wait until I
have some real coax, the speaker wire is probably the weak link here?
Maybe I was just pointing this yagi away from the station I was
listening to, I suppose it would be doing its job then!

Checking almost hourly for that license on the internet!
