## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS318020269:1` (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/SS318020269:1.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

**Features**

- Maximal gain: 2.8dBi
- Frequency range: 868MHz
- Antenna Length: 19.5cm
- SMA male connector
- LoRa-E5 [dev board](https://www.seeedstudio.com/LoRa-E5-Dev-Kit-p-4868.html) and [mini board](https://www.seeedstudio.com/LoRa-E5-mini-STM32WLE5JC-p-4869.html)

Applications for LoRa often include urban environments or large stretches of land which require gateways that can provide extensive coverage. Some LoRa Gateways do not have an integrated Antenna or an antenna that does not provide the required range. For this kind of scenario Gateways can be upgraded with antennas. This LoRa antenna can make a useful addition to your LoRa system. It’s a robust solution to provide extra power and range for LoRa Base stations. The antenna has an average gain of 2.8 dBi, a length of 19.5cm, and a frequency of 868MHz.

The Antenna has an SMA Male connector. It and can be connected to the [LoRa-E5 Development Board](https://www.seeedstudio.com/LoRa-E5-Dev-Kit-p-4868.html)and [LoRa-E5 mini](https://www.seeedstudio.com/LoRa-E5-mini-STM32WLE5JC-p-4869.html). By using an SMA to I-PEX Antenna Cable it can also be connected to the [Grove-LoRa-E5](https://www.seeedstudio.com/Grove-LoRa-E5-STM32WLE5JC-p-4867.html).

**Application**

The antenna can be used in any environment where long-range LoRa connections are required.

- Agriculture
- Environmental Monitoring
- Urban Monitoring
