INNOV 50-70MHz Dual Band Current Balun 2KW

A Ferrite Core Balun fitted with N-type Female - IB6-4H

You will cover either 6m or 4m very well but not both. The dual band Balun will cover 30MHz to 300MHz without any issues ensuring your antenna stays in tune on each band of use.

It can help get the 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.

In addition to the performance drop, coax radiating can lead to causing interference in your home and those of neighbours too. 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.
