提及傷肝的危險因子，很多人都會想到酒精，實際上不只如此。胃腸肝膽科醫師錢政弘就提到，先前曾連續收治2名80多歲的男性患者，均被診斷出肝癌，但皆無飲酒習慣，進一步探究後才發現，兩人有一共同點，就是家中都設有神明廳，每天固定會燒香拜拜，卻忽略通風重要性，成為致病關鍵。

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.

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

醫師錢政弘在《小宇宙大爆發》節目上表示，這2名患者在診斷出肝癌之前，都自認肝臟很不錯，因平時並沒有喝酒習慣，也沒有常見的致病因子，如B、C型肝炎等，後來因身體不適就醫才驚覺罹病。

錢政弘接著說，這兩名患者的共同點就是在家裡都設有神明廳，每天會固定上香拜拜，甚至在雨天時，窗戶也不見得都打開，導致空氣不流通，卻完全忽略燒香時釋放PM2.5的危險性。
