Working off list on a super high performance GPSDO but low cost thanks to a 
 time nut (sorry forgot his name) he directed me to DX.com which have ublox 
with  antenna for lwss than $ 23. Super performance and though they are out 
of the one  with 1 pps all you have to do is solder directly to the module. 
Have both  versions. Attached you see what I did with the antenna but found 
out the hard  way that when it rains the concave bottom fills with water, 
still works but not  as good. So last night I made it flat with 3M Marine 
5200 slow cure that I have  extensive experience with from boating. Will take a 
full week to cure but if it  does not work I can always remove it and start 
over
