[VHFcontesting] stacking 17B2's

All that information is best located in the VE7BQH 2 meter yagi tables which
deal with essentially every decent 2 meter yagi ever designed. This data is
found in several places including

http://www.sm2cew.com/gt.htm

All data is in meters. To convert to feet, go to Google and put for example
the following in the search box:

3.33 meters in feet

and the Google calculator will return the distance in feet

Please note that the quality of a particular yagi is probably best
represented by the G/T figure of merit, the last column. The less negative
the G/T the better the yagi. So for the 17B2 if you have the space you will
get a better pattern and marginally more gain if you use the longer VE7BQH
stacking distance rather than that recommended by Cushcraft. 

I have a single 17B2 and it works well. I believe it was designed by W1JR
when he was chief engineer of Cushcraft. You can't go wrong with a W1JR
design. As you know you will find the 17B2 to be relatively robust
mechanically with a solid support strut and a decent boom.

I have a single 17B2 and am looking to stack another with it, my question is
two fold:

1) What experiences do you have in general, good or bad, with the 17B2's

2) What is the recommended stacking distance for best pattern.

 Thanks, 73 Todd WD0T
