Battery Powered Re-Radiating Antenna

How does re-radiating antenna work?
Re-radiating antenna consists of 2 parts - receiving antenna and transmitting antenna.
Receiving antenna has internal signal amplifier so requires power. Amplified signal is transferred to the transmitting antenna which "radiates" the signal onto the antenna of GPS.

Why do I need re-radiating antenna?
1. You need to put an external antenna where it can "see" more/enough satellites to get satisfactory reception. e.g. inside car so you put the receiving antenna on the roof.
2. In places where reception is marginal, e.g. in woods or streets with high buildings. Because re-radiating antenna "amplifies" the signal so you might get 4-5 satellites when you can get only 2-3 with your handheld GPS with its own internal antenna.
These apply also to external antenna if your GPS has external antenna connection.
3. Many cars now have heated windscreen which can prevent satisfactory reception. An external antenna is almost mandatory in such case.

There are many GPS without external antenna connection. This is where re-radiating antenna becomes useful. As far as we know, all re-radiating antennas on the market presently require cigar lighter socket power so can only be used in car. Even in car, power for re-radiating antenna is also a problem as inevitably, your GPS and/or PDA also require the cigar lighter socket power.

All other re-radiating antennas on the market presently have non-removable receiving antennas. We are the first to make it in 2 parts. It is easier/neater to store as well as more convenient to use batteries than to use car power. We also make it "universal" in that you can use the external active antenna in other GPS that has the appropriate antenna connection (MCX or BNC). Or you can just buy the inexpensive power/transmitting unit and use your own compatible active antenna (see below), if you already have one.

How do I use the battery powered re-radiating antenna?
It cannot be simpler. You need 3 x AA batteries (rechargeable Ni-MH or alkaline). Connect the external antenna, put it somewhere where it has best view of the sky (e.g. car roof). Switch on (LED power indicator  shows it is on and adequate power). Place the radiating antenna loop onto the GPS.
You should see the result immediately (allow TIFF - time to first fix).
For best result, use the supplied rubber band to strap the antenna loop onto the GPS so that it is secure even if you move the GPS about. Characteristics and positions of internal antenna vary so experiment the positions to get best result.

How long do the batteries last?
It depends on the power/current consumption of your active antenna. With our (GAS08X or GAST3B/GAS76B), it last more than 100 hours of continuous use with rechargeable Ni-MH, or up to 200 hours with alkaline batteries. The power indicator dims as power gets low. It is still workable even if it get very dim. When you cannot see any light, it is time to change batteries. (At the end of the battery life, it still has power to light the LED if the active antenna is not connected. The light goes out as soon as active antenna is connected, which shows there is not enough life in the batteries to power the active antenna)

I already have an active antenna, can I use it with your power/transmitting unit?
Apart from the appropriate connector (BNC or MCX), it has to be low powered (15mA or less), and requires power voltage in the range of 3.6-4.5v. Most modern breed of active antennas should be compatible. Please consult your antenna supplier for specifications.
Our re-radiating antenna is optimised for our own active Antenna (GAS08X/GAS76X or GAST3B/GAS76B).
