Ok, I was finally able to open the link. That is interesting this 6M5 to


6M5X conversion. The only thing I see is that the element lengths are


different than the factory 6M5X. It looks like the elements on the older


6M5 model taper or have a smaller diameter than the 6M5X. The one that I


have has continuous 3/8" tube elements. Possibly this is why the element


dimensions are different. This shows me that this beam is not a conversion


model.


I see that they are showing the T match rods to be 12". From this it looks


like I need to cut the rods to 12" on my 6M5X. To be on the safe side, I


should put up the antenna, set the shorting bars to 7.5" and then see what


it looks like. Then start trimming the rods as needed. If someone out


there has a 6M5X that can measure their T Match rods, can settle the


issue. Thanks




I am not sure what effect the lengths of the rods past the shortning bars

would have. Probably not too much if any.

I think I would move the bars about 1/2 inch in and then out if the swr did

not improve and see what hapens before cutting the rods.

Maybe go up and down the band to see what the swr is over the band as about

1 mhz will make a lot of differance in the beam.


Hi Ralph, Unless someone can give me the exact 6M5X T match rod length, I will leave these as they are and assemble the antenna and do the testing as you say. I am thinking now that this 6M5X came from the factory with the wrong T match rods. Thanks, Randy, w5kcm
