Discontinued INNOV 70cms 420 - 480Mhz Current Balun 700W

A Ferrite Core Balun fitted with N-type Female - IB70M

if you just want a much cleaner Balun install then we can help. Ferrite core baluns have a much wider bandwidth than the choke so are far more suitable to wide band or multi-band antennas.

The Ferrite core baluns are fitted with terminal connections to suit your product and are fully water-proofed at the factory being sealed with a glue-filled UV stable heat-shrink prior to dispatch

It can help get the absolute best in terms of performance from any Yagi. It is not understood by many the importance of a balun and what is does so below are a few lines of explanation.

A balun is a Balanced to Unbalanced transformer. The Yagi antenna is a balanced radiator. Coax cable is an unbalanced feedline.

When an unbalanced feedline feeds a balanced antenna with no balun in place, common-mode currents result and run back along the outside of the coax cable. This means the Yagi is forced out of balance causing a skew in the Yagi’s pattern and often a loss of Front to Back ratio is seen in addition to coax radiation.

There is one more very important aspect of using a wideband balun ferrite core types and this can reduce receiver noise levels too in certain instances.
