## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GPS-23848:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GPS-23848:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)

## Description

The BT-T009 antenna is a small, light weight, anti-vandal permanent mount GNSS/GPS L1/L2/L5 multi-band antenna for GPS, GLONASS, Galileo, and BeiDou constellations. Designed more for permanent mount applications, requiring four screws to be installed/deinstalled. Think of it as kind of anti-vandal. The BT-T009 weighs in at =22g grams with a standard SMA connector. This antenna is a good choice for applications where you have a clear view of the sky. If you can handle the extra weight, the [u-blox ANN-MB-00](https://core-electronics.com.au/search/?q=15192) or [TOP106](https://core-electronics.com.au/search/?q=17751) will have better reception performance.

L5 is the third civilian GPS signal, designed to meet demanding requirements. L5 will provide users worldwide with the most advanced civilian GPS signal. When used in combination with L1 C/A and L2C, L5 will provide a highly robust service. While this antenna works great with normal L1 GPS/GNSS receivers it will not make your $20 receiver into a $200 receiver. Please check your receiver to verify it is capable of using the L1, L2 and L5 signals that this antenna outputs.
