多數人認為男生精蟲數量多，女伴就越容易受孕。對此，泌尿科醫師陳昭安表示，一般男性每c.c.精液裡有1500萬隻以上精蟲，但射出來的精蟲，若是「完全不動」或「原地轉圈」都沒用，能夠直線前進的才有用。

The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.

This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.

Double Ridged Horn Antennas are suitable for both transmitting and receiving purposes, with applications:

• - Antenna measurement
• - Communication systems
• - Satellite tracking systems
• - Radar Detection System
• - Surveillance System
• - Electromagnetic Compatibility Testing (EMC test)

Recommended Accessories

• - Antenna Tripod: easy and fast-changing position. 100% stable after installing.

SUMMARY TABLE OF DOUBLE-RIDGED HORN ANTENNA (HA-SERIES) 

陳昭安表示，一般男性每c.c.精液裡都有1500萬隻以上精蟲，一次射精量大約2至5c.c.，每次射出個1、2億隻精蟲，不是太大的問題，精蟲要有用，要看它射出來後能不能動，如果是完全不動，或是原地轉圈，都是沒有用的精蟲，能夠直線前進的精蟲，才是有用的精蟲。
