Exactly. I'll probably wait until NEARfest up here and pick one up there. You
know, more justification to go.

It seems, just go with quad shield RG-6 and be done with it. I even have
part of a spool of that laying around. Maybe more of an issue is how do
you properly connect a TNC to that stuff (the antenna has a TNC).

Here is one solution:

Hi Peter,
Why not. The antenna is optimized for that purpose (receiving GPS L1),
omnidirectional and tuned to the GPS frequency, snow skids down, birds
can't land on it. As N0UU affirms, there's nothing further sensational
inside.
I don't know, how proficient you are with radio frequency stuff, but a
gain of 35dB does not guarantee a good reception. You primarily need
gain to compensate (cable) losses. The noise figure (NF), for example,
can get much more important.
What antenna do you use at the time? If you are using a magnetic car
roof antenna a Trimble Bullet surely will be a better choice...
There are lots of GPS antennas on ebay for even less than 30 Dollars.
I run four different antennas, which I purchased from ebay and none of
them has failed so far.

I'd like to get a better antenna for my Thunderbolt.
I see Trimble bullet antennas type 57860-00 on ebay for $30 or so,
specs look to be 5 volt 35 dB gain.
Would something like this be a good choice?
Peter
