1.75 SWR Acceptable?
1.75 SWR Acceptable?
I installed my Predator 10K with new Belden Mini 8 running a SWP Galaxy 99. The SWR is 1.5 to 1.75 on channels 1, 19 and 40 perceptively. Good enough? Is it that important to have 1.5 or less? Will it make any difference in send or receive running with an SWR of 1.1:1 versus what I have?

First off, the guys are right. Yes, it's better than a 2.0 SWR, but something doesn't seem right. What is it on Channel 1? And what is it on channel 40? That will tell us/you which way to go with the antenna (longer or shorter).
Where is it mounted? Could be some side reflection is taking place, could be alot of things...not excluding the ground not being quite good enough. Whenever I run into an SWR that doesn't seem to stablize one way or another, I look closer at the ground point(s). Sometimes the RF ground isn't as good as it should be...therefor giving some less than desirable SWR's.
Myself, I'm usually not happy until I achieve a 1.5:1 (or lower) SWR across the band. I don't own a 10k (yet), but from all the reports I've seen it should be plenty broad banded enough to achieve a better SWR than you are showing.
Just my $.02
