FQHCC HH-S518 stubby

Introduction

The Author has been making commercial antennas for years. This is a report for a another commercially made one by Fujian Quanzhou Huahong Communication Co., Ltd. The return loss is being 21 db, but way out of band and 2 on 70-cm.

A cable was added in line to change the figures of 5 db on 2-meters (but still out of band) and 6 on 70-cm.

For HT use this is not acceptable. There are other variables to the best (lowest) return figures, such as hand placement and type of radio. For example, some hand-held radios have more metal than others to which the former type helps improve that return level in many cases. This is way below typical on the better subbys. The Author has attempted to contact the Company (in China) recently. Because of the (typical) language barrier there are not high hopes in getting anything meaningfull if there's an answer at all.
