External Gps Antenna

Recommended Posts

We recently purchased a Garmin 60C. I also purchased an external antenna and used it for the first time this weekend on a trip from Washington D.C. to Indianapolis. The 60C with a windshield mount gets great signal locks but I wanted to try out the external antenna to see if there was any difference. The antenna I bought of eBay was only $18, no name, looks like all the other ones out there. All I can say is WOW. Most of the trip the GPSr was showing a signal from 8-10 satellites and 7 of which were showing full strength signal. Cant say that I needed the external antenna but I can say I got a much better signal than without it.

I use an external antenna with my 3+. When in the jeep, I keep the unit on the shelf created by the open ashtray. The antenna sits on the shelf under the dash where the antenna for the optional nav system gets mounted. It works and looks great.

The external antenna that came with my globalsat bt308 pulls in an even stronger signal than the unit itself, which is impressive anyway. Since the unit gets adequate signal just sitting on the dash, i don't use it in the truck, so the external antrenna is taped to the shoulder strap on my caching backpack, and the unit chills inside the pack when i'm out caching. having the external antenna sit on top of my shoulder gives me great field accuracy.

 

(the bt308 is a bluetooth gps, it streams coordinates wirelessly to my palm pilot, which is why the gps itself is in my backpack)

 

actually, the external antenna is so good at picking up signal, once when my backpack, with external antenna attached, and gps inside it were behind the seat in my truck, i turned the palm pilot on on the dash and found that i had a 3D fix on my location.

 

in short: it's been my limited experience that external antenna do better in all situations

BigWhiteTruck which palm PDA do you use? do you have it in some kind of protective case while out on the trail?

 

yours sounds like a very flexible setup.

I use a Palm Tungsten T3. And no, no case.

I probably should get one. . .

Proporta has a very nice aluminum case for the T3. I have one, and had one of their cases for my Zire 71. Highly recommended. I carry my T3 in my hip pocket most of the time, and never worry about it. Without a case, I'm always worried about it.

I bought one of the Gilssons from GPSgeek on eBay, and I use it on the boat at work, it sits outside on a second deck handrail to get a clear view of the sky. We are always out in the middle of nowhere on the Lower Mississippi, and I'm always showing an accuracy of +/- 6 to 10 feet.

Know of any for a Magellan Meridian Gold? Mine REALLY needs an external antenna but I am having trouble finding one.

Have a Garmin Map76 and also purchased a no name external off of E-Bay. Works great.

 

One caution, if your vehicle has a compass, don't attach your antenna to the roof. Use the hood or trunk lid. The magnetic attachment magnetized the roof and messed up the car display. Had to re-set the car compass. As long as the antenna is attached to metal not directly connected to the roof, things work fine.

  PC-Mobile has one that will work.

 

Unfortunately, it looks like all of these require the GPSr to have an external antenna port (which the Mag. Meridian Gold does not). Does anyone know of one that specifically works with the Gold?

A reradiating antenna does not require that your GPSr have an external antenna port. It works by retransmitting the signals from the satellites through a small antenna that you place in close proximity to the antenna of your GPSr.

Yeah....I actually did some reading on them and they seem pretty cool/good. I've ordered the "GART3X" from pc-mobile.net. I'll post when I get it.

 

Thanks to all for your replies/help!
