Introduction
The Author has been making commercial antennas for years. This is a report for a another commercially made one that comes with the Kenwood TH-F6 radio.
The return loss is 7 db on 2-meters, 15 on 1.25-meters and 10 on 70-cm. For HT use this will probably work in most cases. The Author would recommend this antenna however is very expensive and has to be ordered from Japan.
