Hi Rob,
All things being equal, a 3db antena has a more "ball" shaped range wheras a 6db has a "squashed ball" hence further penetration around the perimeter but less if the antenae is not horizontal.
If you were comparing a 3db broomstick with a 6db broomstick, both the same length and mounted the same way then yes, the 3db "should" perform better in hills. However, comparing a glass mount to a broomstick, the broomstick will win every time regardless of db rating. Now if you put the glass mount on a 1m pole, then you "may" have an advantage in the hills, but kinda defeats the purpose. The CD 1795 6db broomstick is a great all rounder, not worth swapping and changing IMHO (would be a good choice for you Willie, its only 860mm tall including spring and its the same height as my roofline when mounted on the bullbar - a great test for low branches)
As for the difference the car kit makes, its chalk and cheese!!! The best example is when in my garage (double brick, concrete slab roof and roller door down) my Nokia mobile has only 1 bar signal strength (my Kyrocera had none but still in range). When I put the phone in the car kit, it goes to maximum strength.
I was recently ~90 kms on the south western side of
Coolgardie in the middle of the bush (very flat terrain) when I came into CDMA range. Not sure where the tower actually was, but I was happy to be in CDMA range that far out.
I would "estimate" the car kit at minimum doubles or triples the range of a CDMA phone compared to on its own. Even more if comparing while driving (ie not standing on the bullbar trying to maximise reception of the handheld).
Note that the above is my real world experience, technical specs "may" not necessarily agree, but its what I have found.
Cheers
Captain
