## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SS114990711:1` (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/SS114990711:1.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

RF Explorer RFEAH-25 is a 25mm diameter, high performance near field H-Loop antenna. RFEAH-25 is a very sensitive, compact and easy to use H-loop near field antenna. The low-loss design exhibits at least 10dB more sensitivity in the range 20-6000MHz than other H-loop options in the market, at a much lower cost. Compared with other near field antennas, RFEAH- 25 is smaller and lighter, exactly what fits best when space is constrained in a PCB. Included with the antenna is high quality semiflexible RF cable , this cable works as the handler of the antenna. The big advantage of this approach: you can shape the cable the way you want for the antenna to be located exactly where you need it, in most cases with no need to hold it in your hand.

**Features**

- Robust calibrated low cost H-loop near field antenna
- Can work with RF Explorer Spectrum Analyzer, Signal Generator and other RF instruments and devices
- Easy to use, reliable to find interference sources with high accuracy and resolution
- Can be used to detect hidden bugs and transmission sources with great spatial resolution
- Feasible to generate interferences with Signal Generator and confirm RF circuit sensitivity

Capable of pre-EMC compliance tests

**Specification**

- Connector: SMA female
- High frequency RF SMA Male-Male included
- Type: H-loop near field
- Characterized response: 1MHz to 7Ghz
- RoHS compliant

**Part List**

- 1 x H-loop near field antenna
- 1 x Semirigid SMA Male-Male RG402 10cm 6GHz cable
