Hi SangHyoeg: If you want a good introduction to antennas, designed for the non-professional (typically, ham radio enthusiasts), I suggest "The ARRL Antenna Book for Radio Communications”. As an engineer, you will find the material easy to read and understand. The book will give you

Hi 1) Center frequency​ 1.5 Ghz. ANT500 performs well from 75Mhz - 1 Ghz. Outside its optimal range, you can find better antenna. 2) Center frequency 325 Mhz. This is within ANT500's nominal range, but outside your board's range. You will have problems with your board. As Marcus Muller

​Hi, There is no problem using these antennas with your board, as long as you terminate them correctly, 50 O. You choose your antenna based on your coverage, not your board. So what coverage do you need? BR, Nikos On Tue, Mar 22, 2016 at 1:39 PM, SangHyuk Kim wrote: >

Hi, I'm using CBX daughter board which supports from 1.2GHz to 6.0GHz with ANT500 (from 75MHz to 1GHz). Actually, I didn't know this antenna coverage. I have two question. i) Is there any problem when I use ANT500 with CBX ? I have tested QAM and QPSK performance using OFDM using those devices
