Anyone have a Gulf Alpha 70cm 8x8 CP antenna?
I’ve lost the instructions on how to properly place the driven element shorting blocks. I’ve tried using my SWR meter but with no good results.

Go to http://www.gulfalphaantennas.com there's still pages with tuning/assembly instructions.

Thanks Dave. Unfortunately there isn't assembly/tuning instructions for my specific 70cm 8x8 CP antenna on that web site. Hence, my query to the AMSAT-BB.

Bob,
Copy and paste from one of the Gulf Alpha pages...
5. Slide the shorting bars onto the T match rods and driven elements. Set the distances as follows for lowest SWR:
2 Meter part: 3 ¼"
70CM part: all the way out (this is the setting for other brands of UHF antennas as well)
The above distances are measured from the inside face of the shorting bars to the end of the T matchbox, not the end of the black bushing. Dave-KB1PVH
