RFI To Upgrade All Base Station Antennas to 4.3-10 Connectors

Starting next month, RFI will begin upgrading our base station antennas by integrating them to the 4.3-10 connector.

The 4.3-10 connector is a game changer for crowded antennas sites, offering increased PIM performance and increased reliability in a compact, easy to install connector.

The first antennas to be integrated will be 800MHz and UHF Corporate Collinears as well as UHF Arrays and harnesses. We will continue to rollout the integration our entire Base Station range throughout the year, with our the completion by mid 2021.

The improved design of the 4.3-10 connector provides far better PIM performance in a smaller size than the DIN, without the dependence on torque to make the best connection, further to this, the need for more connections on the same amount of real estate per antenna, meant something smaller, more reliable and easier to use needed to be designed, therefore, with the design of the 4.3-10, most of the performance issues relating to the DIN have been addressed.

The New 4.3-10 Connector

  • Does not require the tension of the nut to form a good electrical connection.
  • Utilizes a radial contact similar to that of the inner pin
  • The o ring has been moved to the side wall, un-obstructing the final connection, while forming weather seal.
  • The radial contact of the outer conductor means good electrical contact is made before the nut is applied. With the final torque applied; thus ensuring a solid, long term connection.
  • The relocation of the o-ring and compact size reduces need for torque by 80%
  • Only 5Nm required for correct termination

Current Old School N type and DIN Connectors

The electrical performance is independent of the mechanical connection, thus making these old school connectors rely on the torque for a good connection (the tighter the better). With current N types – this makes it harder to achieve reliable resistance to PIM. With current DIN connectors the max torque is essential to make enough compression of the outer contact surfaces to achieve low PIM levels.
