## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GPS-27500:1` (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-27500:1.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.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The u-blox ANN-MB2 multi-band (L1/L2/L5/E6/B3/L) active GNSS antenna is designed to reduce time-to-market for modern wide-frequency, multi-constellation, high-precision GNSS applications. Even in challenging environments, these require centimeter-level accuracy and a reliable RTK positioning fix. Its robust design, excellent price-to-performance ratio, and flexible mounting options make the ANN-MB2 an ideal choice for mass market applications requiring an all-band high-precision GNSS antenna.

The ANN-MB2 is a perfect match to the [u-blox all-band X20 high-precision platform](https://www.u-blox.com/en/x20) (e.g., ZED-X20P), and the u-blox F9 high-precision products that support L1, L2, and L5 bands, along with the L-band for RTK corrections (e.g., ZED-F9K, ZED-F9P, LEA-F9T, and ZED-F9T). With ANN-MB2, customers have a reliable, ready-to-use, all-band antenna that streamlines evaluation, minimizes design efforts, and speeds up mass adoption.
