First Time making antenna(s)

[masterkeymaster]

I need to make around four J pole antennas for the following frequencies 50.125 Mhz, 123.0 Mhz, 156.8 Mhz, and the other at 509.8125 Mhz.

Can some one give me guidance, I will be using copper piping with a so 259, what do I need for the dimensions? I know that the so 259 jack and the female will be movable until I am done.

After they are complete I will heat shrink them to protect them from the outside elements.

I do have a MFJ-269 Pro

Have you tried 'googling' for your answer to those dimensions? I'm afraid there are not 'fixed' answers to your question, all antennas have to be 'tuned' for use. That means getting 'close' then adjusting things till it's as 'right' as you can get it.
Not a very satisfying answer, huh?
