Introduction

This mini size band reject filter has a rotating male F-type connector for easier installation, especially in tight spaces.

It is designed to pass the CATV Return Path (e.g. 5-42MHz, 5-65MHz, etc.) and UHF Band signals and reject all other CATV channels (e.g. 55-500MHz, 85-550MHz, etc.).

The electrical specifications are, as can be expected of Soontai, excellent, with a low insertion loss, high rejection and excellent return loss.

On top of that you get a waterproof filter with very small dimensions that is CE certified and has class A RFI shielding.

This filter can be used in any 5-1000 MHz RF application, testing equipment, etc.
