I recently purchased a powered monopole that came with an antenna, it has 6 elements 2 each on 10,15 and 20 the boom is in three sections there are no traps, the antenna is all riveted and only the 20m element is driven, one thing is the brackets to mount the elements to the boom are well made and are u shaped and also riveted to the boom.
The elements are mounted in a plastic sleeve and then mount on the brackets.
the boom is only around 12'.
I do not know how to post photo's in this forum (some help?) but I can email some.
Please some assistance.

Sounds like a Force 12 three band C type antenna.  They make several with 12 ft booms and use riveted construction.   C-3S, C-3SS, etc.  Do a google on Force 12 antennas and look at their site.

Yep, it's the baby Force 12 Yagi.

The bigger ones have 7 elements and the booms get longer.

Only Force 12 uses a single driven element to excite all bands without traps, and also riveted construction.

Easy to assemble, not as easy to disassemble!

:-)

Built many of them.

Definitely a Force12.  I have had the C3SS for over ten years, and love it.  The front-to-back is not so hot, but other than that it's done very well for me at two QTH's.

Only the 20M element is driven directly, but it is (or should be) connected to the 10M and 15M driven elements with jumper wires.  If the jumper wires aren't there, it's not going to work well on other bands.  Also usable on 17M and 12M with a tuner.

73,

Thanks all!

I managed to send a couple of photos to Force 12 and they sent me the manual, considering what I paid for the tower and antenna I got a great deal!

Have a great day all!
