  • Select

Standard gain horn antennas are used as calibration devices that measure the gain of other antennas.

These antennas are made up of a combination of a Waveguide to Coax Adapter and Standard Gain Horn with Waveguide Input. It is a kind of simple combination but with great care and attention to create an antenna with accurate and suitable specs.

FT-RF Standard gain horn antenna product series includes waveguide sizes WR28, WR42, WR51, WR62, WR75, WR90, WR112, WR137, WR159, WR187, WR229, WR284 and WR340, WR430, WR510, WR650, WR770, WR975, WR1150, WR1500, WR1800, WR2100, WR2300, with broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.

Standard Gain Horn Antenna Applications:

  • - Antenna measurement
  • - Radar Detection System
  • - Wireless Communication

一名患者的左腳時常感到麻麻的,結果檢查後才發現罹患大腸癌。(示意圖/資料照)

腳麻總讓人不舒服又困擾,而有時候「麻」跟「痛」其實是身體給我們的警訊。外科醫師陳榮堅曾分享,一名患者的左腳時常感到麻麻、痛痛的,認為應該是坐骨神經痛,但檢查後才發現是大腸癌,合併脊椎、肝臟同時轉移,這樣的情況不適合手術,只能用化療跟標靶治療了。

陳榮堅曾在臉書發文表示,沒有典型症狀,卻已經癌症轉移?癌症侵襲常見有兩種情況,一種是腫瘤在原地慢慢的長大;另一種是腫瘤在很小的時候,就喜歡「四處流浪」。

陳榮堅指出,有位50多歲的女性患者,因為左腳時常感到麻麻、痛痛的,認為應該是坐骨神經痛,所以來他檢查,但檢查後發現,她的症狀不太像一般坐骨神經痛導致,進一步檢查發現原來她是大腸癌合併脊椎、肝臟同時轉移。broadband waveguide horn antennas have frequency capabilities ranging from 320Mhz to 40 GHz depending on type and style. with the gain of 10dBi, 15dBi, 20dBi and 25dBi.

陳榮堅說,患者自己也非常錯愕,因沒出現排便不適等典型大腸癌症狀,雖然大腸癌病灶才2公分多一點點而已,但脊椎、肝臟已經都有轉移,甚至肺部也疑似有轉移,這樣的情況不適合手術,只能用化療跟標靶治療了。
