【Features】

●

HF band coil is added ba

ed on 50MHz band, 144MHz band and 430MHz band.

An antenna that can operate in up to 9 bands.

●

The change in the center frequency fo shi

between the 50MHz band and the

144MHz band due to the inﬂu

nce of the HF band coil installa�on is small,

and any combina

on can be easily operated.
