The gist of it was, this guy runs a similar antenna setup to yours. He achieved some analyzer numbers, using RG-213 18', that were to die for! Said he tried every other type coax and this got the best results. Might be food for thought....
Yeap good #'s for sure but based on a book i have from arrl his return loss is twice what a perfect set up should be and r# is good but across from that the readings seem high.. Lastly he is gettin that reading from the radio end of the coax. Not sure how that affect the true # @ the antenna.... My aa 55 zoom allows me to recalibrate to read at the antenna which shows different readings than it would from radio side of coax.... I saw his thread an hr ago and he mentioned a brond strap from his bracket to firewall i think and that affects a true reading again... How much these things affect the actual ant performaces i cant say for sure but its almost to good to be true in my thoughts based on what i know... Not sayin his set up is wrong or bad but just a few things im not sure about based on my experience..Oh and his 213 vs my lmr 240 wouldnt make a huge diff either. What ever my issue is,its something stupid im not seeing cause i had better results before on my previous plascadia..
