[d-star] Antennas - 1.2

We have several GP-21s - they are the ones I don't like - wobbly bases etc 
GP-98 is a longer, 2 piece version of the GP-93 which is a rare bird 
The MFJs are indeed mongrels

Erik,
 
FYI......
 
You do know, don't you, that MFJ acquires those "Pulsar" antennas from  an 
OEM supplier, i.e. Comet? Diamond? Whoever? (MFJ makes many of its
antennas, 
but not those.)
 
Also, you might want to double check the model number of the Comet  
antenna.....according to my old catalog and the NCG website,  it's GP-98,
not GP-93, 
i.e. tri-band, 144 mhz, 440 mhz and 1200 mhz, 9'8"  long with a claimed 1200
mhz 
gain of 13.5 dbi.  
 
Also, if you're looking for a 1200 mhz only antenna, Comet offers the GP-21

which covers 1240-1300 mhz.  It's 8 ft. long - -  claimed gain  somewhat 
better than the GP-98 on 1200 mhz band....21 1/2 wave elements for 14.9  dbi

supposed gain.

We have  a few rooftop repeater sites lined up and want to get some antennas
for  stock.  We are constrained by height and visibility.  I just ordered
an
MFJ-1532-N from Radio City, and am working on a Comet GP-93 from  them.  I
am
not a big Comet fan as our in service failure rate has  been high.
