RECOMMENDATIONS ON ACCESSORIES

• In order to improve the efficiency of this GP antenna, having radials are very important and especially for M-104, since it sacrifices the efficiency to meet the portable size.
• It’s recommended to have antenna analyzer or VNA to be able to read the parameters of the antenna set up.
• Of course it will be great if you have an antenna tuner
