- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CAB-21739:1.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.

## Description

This is a 300mm (1 foot) Male TNC to Male SMA cable with injection molded stress-relief boots. This is an excellent cable for connecting one of our RTK development boards to a high quality 'UFO' style GNSS antenna. Able to withstand harsh environments and field-use, it's long enough to connect to a device located on a monopole or tripod without having too much extra cable.

The SYV-50-3 cable has a loss of 52dB per 100m (320ft) or 0.16dB of loss per length of 300mm. Sparkfun specifically chose SYV-50-3 cable over RG58 (46db per 100m) for its good balance of low loss and high flexibility.

Each cable has a nominal impedance of 50O. If you are looking for a good antenna to pair this cable with, Sparkfun recommend our [GNSS Multi-Band L1/L2/L5 Surveying Antenna](https://core-electronics.com.au/search/?q=21801).
