Default Antron 99 top section


A friend gave me an antron 99 bottom and mid section. Can a 6`or 8`francis whip or firestickor even a 102 steel whip be used? Or would it be better to find a top section?

I know that Firestick Make`s a top section for the A-99.

Fire-Up 99 Antenna

I have never used one, but I do not see why it would not work.

When I was a child
I caught a fleeting glimpse
Out of the corner of my eye.
I turned to look but it was gone
I cannot put my finger on it now
The child is grown,
The dream is gone.
but I have become comfortably numb.

If you can find out what the length of that top section is, and replace it with something of the same length, it should work. If you replace that top section with a wound whip then it will probably be too long, the matching rings probably won't be able to 'match' the antenna.

I've run an A99 with a steel whip and also with a Francis Amazer. Both worked very well. I thought that the steel whip was a tad better but not by much. No experience with the Firestick.

the fire up a99 top section would work great. or any other 5-6 feet long fiberglass
top.

I think most of the antennas you mention are 11 meter resonant antennas, and the tip element on the A99 is not resonant at 27 mhz, so the answer is no.

However, the bandwidth of this antenna is so wide you'd probably never notice with such an addition, excepting maybe that the antenna would then show to be lower in resonance at the best SWR...if you really checked it out.

The replacement tip Fire-Up 99 Antenna note by Jeff, claims to make the A99 a 5/8 wave antenna, which IMO is CBBS, but it seems to work according to reports. You will note in the link that this element is not resonant.

since the wire inside the sections is straight , could a 102 cut to the same length be used ? someone found a 99 in their stuff and gave it to me . the top section measures 69 1/2 inches from the top of the element to the bottom where it sits on the rest of the antenna (not including threads) .

The top element on my A99 is 72.25". I wonder why the difference BM?

Does your tip elements have a rubber cap with Antron printed on them?
