Just about anything will work. The most important thing, more important than the type of antenna is LOCATION. If you have a clear view of the sky and can mount the antenna on a 3/4" galvanized iron pipe mast then the in-expensive "pointy" 26dB ant. works well (180518378555) These will mount on an iron pipe flange. Some flanges even have the holes in the right location and then you lead the coax down the center of the pipe and everything is 100% weather proof. You should ground the pipe and maybe think about lightening too.
I like "N" type connectors for outdoors. They are water tight and resist corrosion for decades especially if the connector is inside a waterproof pipe. I glued some automotive gasket material to the pipe flange and used stainless bolts. My experience is that such a setup will last "forever". I think the "N" type is worth it for a permanent outdoor installation even if it does require a more expensive coax cable. That said, even a cheap patch antenna works. The t-bolt cares more about what it can see than about gain. Also good to be away from reflections that can cause multi path. That is why I like the pipe mast. It place the antenna is free air. You can strap it to a vent pipe on the roof. I like the pointy top design too. Keeps birds and bird poop off the radome. Snow is not a problem here but if it is at your location the pointy top helps with that too. More gain might be nice if you are looking through a window, trees or whatever. But gain is not a substitute for location. On Sun, Apr 29, 2012 at 9:29 AM, Ken Kubick <[email protected]> wrote: > 180518378555 > Hi, Time-Nuts guys I just baught a Trimble Thunderbolt on ebay.
