Notes for Using the Antenna
To avoid accidents, follow the below notices
1. This antenna is designed to use the car body or the metal handrail as the ground earth when the portable use. Do not
install the antenna fixed and on to the transceiver all the time due to the issues of the product strength and waterproof. This
antenna is prohibited from using for mobile, due to this antenna is not prepared for strong winds.
2. Do not touch the antenna during transmission. Touching the antenna during transmíssion may cause to electrify depending
on the power used.
Description
1. The HF-PRO-1 can be operated on wide band 7-430MHz. lt is OK to use the HF-PRO-1 only when portable operation.
2. If the frecuency adjusted is a higher value, lower the rod element.
3. 144MHz band can be operated at both 1/4 wave and 5/8 wave depending on the lenght of the additional element used.
