Does anyone have the instructions for an AEA Isopole for 2 meters?  I have one of these antennas that has never been used but I have lost the instruction manual.

Jim,

If you'll email me with your snail-mail address, I'll drop you a copy in the mail.

Whoops!  Sorry, can't help after all.  I have the AEA Iso-LOOP.  Mis-read your post.

As I recall, the "instructions" only told you to set the radiator tubing length and clamp on the aluminum sheet (cone-shaped) decoupling skirt to the support mast directly below the antenna feedpoint.  You feed the coaxial cable through the support mast, screw it into the base of the antenna, then slide the antenna down onto the mast, tighten it, and use a stainless steel hose clamp to secure the aluminum cone-shaped skirt to the mast right at that point.

The antenna has no adjustments at all, except for radiator length, which is adjusted by sliding the aluminum tubing inner section inside the outer section and tightening the hose clamp once the correct length is found, using an SWR bridge to determine resonance.

I have one of these antennas. I use it at my home to talk to dispatch and to other officers via police frequencies. It works well I can with a 45 watt motorola radio contact the police cars very well and can with the antenna up 40 feet talk to  a county that is seperated by a county from me. Our counties are 36 miles wide. It works well however I have a yagi for both ham radio and the police freqs. and it works better for contacting departments via radio.

The only adjustments are the positions of the two
cones and the length of the top radiator.  Just be
sure to use some anti-oxidant grease on the joints,
or you won't be able to adjust the radiator length
after a few years in the air.

Thanks, but what I need are where to put the cones on the mast.

I can't pull mine down to measure it, but will see if
I can find the dimensions.

As a start, the BOTTOM of the TOP cone should be the
same distance below the feedpoint as the length of the
top radiator, and the bottom of the bottom cone should
be a quarter wavelength below that.

(The actual antenna is the section from the top of the
radiator to the bottom of the upper cone - this should
be 2 x 5/8 wave.  The lower cone just serves to
decouple the mast from the antenna currents.)
