To those that say a few db extra cable loss does not make any
difference consider the following:

Every time you double the height of your VHF antenna you gain 6 db in
signal strength.

Never heard this...any sources I can refer to? None of my books suggest this.

If true...
5 to 10 feet = +6 dB
10 to 20 feet = 12dB
20 to 40 feet = 18dB
40 to 80 feet = 24dB
80 to 160 feet = 30dB, which is 1000 times the power supplied at the transmitter end of the cable.

6 db signal strength increase at 30 miles accounts for about 3 extra
miles in range.

Can you please show the calculations? Or a pointer?
