#1 Go for Height.
#2 Go for antenna gain (helps Receive and Transmit)
#3 Power - probably should not have much more erp than the users will have talking back...
Height is great up to a point. Once you get past 400 to 500 feet, the horizon doesn't get much further out without a substantial increase.
Antenna gain helps both RX and TX, but be sure the pattern and location of the antenna works for the desired coverage area. Lots of coverage over a lake might not serve many folks...A very high gain antenna may hurt close in (particularly in building) coverage while directing more signal 15 miles out....

Easy question for all other repeater owners. What should I do?
I have a pair of folded looped-dipole antenna's for my repeater which
pushes 42 Watts. Once I add the antenna and duplexers I get 25 Watts
output. The antenna has 4 looped-dipole antenna's with phasing
harness but I only use one set.
So what should I do, should I continue using the 1 set of
looped-dipole antenna's at 25 Watts or do I add the second pair of
looped-dipole antenna's and push only 10 Watts out on the repeater (As
there will be a loss).
Which would be better? I am sure I am doubling the gain for PEP.
Would I have a better receive on the antenna as well? Would it really
make it stronger?
