"I am making a J-pole out of 1/2 inch conduit."

There ia a 144 MHz Super-J in the "ARRL Antenna Book". It`s on page
16-24 of my 19th edition. Individual piece drawings and measurements
are presented for novice builders.

The "Antenna Book" Maritime Antenna is "Super" because it is a collinear
using (2) 1/2-wave sections, in phase, and end to end. For a simple
J-pole, eliminate one 1/2-wave section and the 1/4-wave phase-inverting
stub.

Stainless steel is used fotr the "Super J-pole", but rustable steel can
be used if deesired.

I would like to see that stainless stell version. What size tubing does
it use?

What is a "super" j pole?

I would like that book but am a little strapped right now. (One reason
I am using conduit). We just had our second child born January 2!
Maybe I can get it at the Library?

Do you think my construction would be ok? WIll supporting the antenna
by the crossbar cause any problem?
