Is there any simple and easy way to build a 3 element beam ? what do i need and whats steps? i want to talk long distance and i dont have alot of power im runnin a cobra 148 and a palomar 250tx from what im being told if i use a 3 element beam it would be better dx'in than my a99 thanks

Simple 3 Element Beam

Simple way?
No . . .
It stops being simple when you understand that the 'Gamma Match' device is a special piece hardware. Not saying building a beam from scratch can't be done. But for the cost of a commercial 3 element beam and what it wold take to accumulate the materials, time spent, and being able to get it going the first time around - I would just buy the beam.

Maybe consider a two element quad antenna. Can be built for less than $20 with materials from your local home supply store.

2 Element Cubical Quad for 10 or 11 Meters by N1UUE
You really would not see any difference in performance in transmit or receive from two element quad to a three element yagi.
The quad is more of a mechanical challenge to build, but for cost vs performance it is a great low cost antenna that performs well.
A 1/4wl with velocity factor of 75 ohm cable tv coax RG6 or equivelant will make a nice matching transformer to get the impedance to 50 ohm or acceptable VSWR.
Google is your friend for this information on how to build.

Hello,
There are several ways to make a direct 50 ohms impedance yagi where no matching is needed.
A example can be found here:
Skypper
Another example can be found here:

Good to see you here Henry, also the Moxon but it is only two element, more can be added if builder wants. Good 50 ohm impedance.
