[time-nuts] GPS antenna in attic?

[Peter Gottlieb]

The antenna I got fron Nichegeek on ebay uses British Pipe Threads! Just can't 
get anything here that matches it.  Perhaps I should just get a unit with 
regular NPT size threads?  Can anyone recommend a specific model which works 
well with the Thunderbolt and has such a threaded bottom?
