FWIW I have both a Raider and a 1.2m shakespere 'glass whip. It;s a long story involving the mounts and a garage door, but ignoring the proactialities of my A- frame, I have both, patchable insiode the console.
Now, I grant you I donlt do the sort of Long distance some on here do, but about 5 years ago there was a variation of this thread which if memory serves went on to show that the older models of Raider had what some might describe as a fundamental water ingress issue. Mine os one of the newer design, and even after smacking the top of the garage door a good few times (hence the two of them - the folding bracket was cheaper to buy in a long bag with a whip antenna
I rthen opicked up another folding mount...but I digress.....
Bottom line- Reception difference? - immesurable. TX difference - not had to repeat anything more with one that 't'other.
I think I have the Whip hooked up at the moment - the difference is so great I'll need to go look at the patch panel to see which one is in use!
I do feel we can get overly deep on arguing the theory in here sometimes.....
