No post is ever old Today I put the new Sirio 4 element up and used the exact measurements in this post. 1.2 across the entire 11 meter band. Thanks again to everyone that posts.I purchased a new 4 element sirio. I notice the factory lengths of all elements uncut are set for 26.500 mhz.
I don't want to have to cut the ends of each element. The manual gives a cutting chart for 27 mhz, 27.500 mhz, and various 10 meter frequencies.View attachment 26345 View attachment 26346 View attachment 26347 View attachment 26345 View attachment 26346 View attachment 26347
I was wanting to use this for the CB channels and possibly up to 27.555.
Will post pictures of new manual. The one on Google was pre tunned for 27.200 mhz. Totally different than mine.
I'm going to build it and not cut anything and see what happens,
then go from there.
