Default Home Brew Yagi

o.k., so i could not find a antenna that i thought was worth the cost, to receive what i wanted, so i decided to build my own.

I built this antenna using a Yagi-Uda calculator i found on-line, there are a bunch of them available, i just picked one and went with it.

My main low reception area i am trying to gain signal on is 158.000 - 159.000MHz so i built this antenna using the calculator at 158.500MHz.

List of materials used to build this yagi:

1) 3/8" Rigid Aluminum Tubing, 3/8" O.D., .305" I.D, .035 Wall $5.52 ea. total = $11.04
2) Polythylene (LDPE) Rectangular Bar 1" x 1" total = $5.75
3) 1 1/2" Cush-O-Clamp $2.70
4) Rubber end caps FREE (from work)
5) 6/32 stainless hardware FREE (from work)
6) Small stainless hose clamps (for the driven elements) (free from work)


Total Cost of build = $19.49 (the stuff from work cost very little to buy even if i did have to pay for it myself)

If the weather holds off tomorrow i will be raising to 50' and see if it picks up my low receiving stations.
After checking the performance, I plan on building allot of my own freq, specific antennas, it much cheaper to build then to buy, as long as you pay attention to cutting length and spacing details, i guess i will find out how well i paid attention to details when i put this up.

Pics of the antenna up in the air will follow,as well as information as far as if it worked for what i built it to do.

So here is what it looks like.
