Decided to build and big yagi for local MARCS.
Should work between 800-900MHz
Antenna centered at 850MHz.
23 Elements
Overall length 6' 9"
Total weight 3.8lbs. (amazing)
Construction material
1" x 1" x 3/32" square aluminum tubing (main section)
3/16" x 1" aluminum flat bar (for joining the 2 sections together and adding strength)
3/8" O.D. round tubing (elements)
rubber end caps
buna (rubber) grommets (for isolation)
8-32 hardware (for mounting the flat bar)[plan to replace with stainless before mounting in the air]
Total material cost -> approx. $45.00
Project just about completed.
Here are the pics.
