[NLRS] Give away + Need advice on DirecTV dishes

[Donn, WA2VOI]

Hi David
It does make sense (the multi-band idea).  As you point out, its 
not optimal especially at 3.4, but sometimes the utility of one 
antenna makes up for a lot of other sins.  Usually, you'd 
optimize for the highest frequency, but you might get a tad more 
gain at 3 and 5 if you optimized there instead.  Depends  on 
where the most Q's can be had, I guess.

My TRW Antenna calculator says to expect ~31 dB on 10GHz (which 
is pretty much what we measure on those), about 26dB on 5.7 GHz, 
and 21 db on 3.4 GHz.

I look forward to seeing the multi-band dish on the antenna 
range.  (Assuming the WX is such that we can do another antenna 
range.  We got skunked at Aurora last month and next week's make 
up is iffy with the WX pattern we seem to be in.  Maybe later in 
the summer....
