Here is what I ended up building:

The one designed for 446mhz

I used a 3/4 by 1.5 inch beam and 1/8th inch brass welding rod with #12 copper THHN wire for the director and reflector.
Works great even with the 8 foot 75 ohm feedline directly wired

Anybody have any ideas on how to improve?

Considering the materials you have to work with, do a Google search on
"quagi antenna". Simple to build and no matching problems.

I would like to build a yagi for 448 mhz rangr for home use I have a 12
foot
1x1" piece of cedar and some 10 gauge copper wire It measures 0.15625" I
think it is 10 gauge. Am I wasting my time? Also how do I use 75 ohm
line
as a feed line? All the plans I have found are for 50 ohm feedlines. It
is
all I have for wire and living out in the boonies it is difficult to
travel
to pick up some 50 ohm.

I'm on a budget / disabled and would appreciate any help/
knowledge/links/donations on this.
I own the ARRL Antenna book 20th edition and find it to be a bit
overwhelming so far.


Cheers,
