[TowerTalk] C-19XR vs TH-6

Hi All:
As every one is having fun with the C-3 vs T-6 debate,
here is a question to add to the pot.

I have a TH-6 at 72 feet. I am thinking of replacing it
with a C-19XR.
How would these two antennas match up?

>From Force 12's web page:

       C3             C19           C31
20     4.6     (-.6)  5.2    (+.8)  6
15     4.8     (-.2)  5.0    (+1.3) 6.3
10     4.4     (-1.5) 5.9    (+1.5) 7.4


>From Steve and Ward's measurements (plus some "funny math")
The math is mine so flame me not the other gents.

       C3         C19         C31      TH-7
20     3.3    (3.9 to 4.1)    4.9      3.0
15     4.3    (4.5 to 3.7)    5.0      3.5
10     2.7    (4.3 to 4.5)    6.0      2.9

It seems to me that the C-19 would be a good substitute 
for the TH-6 
The C-19 wasn't tested but I made the assumption that F-12
tested all their antennas the same, and that the gain figures 
would hold up under the tri-band report's protocol. 
The other assumption I made was that the TH-6 would be quite 
close to the TH-7.

So am I all wet?
