Bob, I just checked on my I-10K's asymmetry in the radial area and it is worse than I remembered. The top radial is 1" inch offset from the middle of the radiator and the bottom radial is not only lower, it is 1.5" inches offset due to being on the outside of the mounting bracket.


My I-10K model is setup symmetrical. I made it offset at first, but the model just never looked right in any category. I thought it was because I added the matcher, but over time fiddling with the dimensions...I decided to fix the offset and then the model's matcher started responding nicely.


I don't know how that effects the match, but it is bound to have some ill-effect that needs to be compromised in setting the match.


Maybe that is why we use to complain to Jay about the resonance and the best SWR seeming to be at the opposite ends of the CB band.


Have you seen any promotion of the new "Shockwave" version of the I-10K with the trombone at a 45* degree angle to the radials? That guy fixed the asymmetry in the radials setup nicely.
