全猿主場 有臺大PM學程身影 400師生 留下家庭日美好回憶

In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection.
Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality.
Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks.

A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location. Two U-bolt brackets and waterproof were supplied in one piece of packing

全猿主場 有臺大PM學程身影 400師生 留下家庭日美好回憶

(中央社訊息服務20220829 09:26:21)在臺灣，要說能有一種運動可以一口氣凝聚近400位各行各業菁英的人氣，棒球應該是第一選擇了。8月27日傍晚，睽違兩年的臺大 PM 家庭日活動，在桃園樂天棒球場熱鬧展開；PM家族成員與眷屬們，組成了一支超大型啦啦隊，在現場為支持的球隊歡呼加油，也為自己平日繁重的工作、生活與課業壓力暫時紓壓。

這場活動由臺大進修推廣學院 PM 學生會主辦，臺大PM校友會以及臺大進修推廣學院協辦，並號召歷年臺大 PM 校友及在校生共襄盛舉。臺大PM學生會包下球場本壘板後方的最佳位置，邀請中華職棒前會長吳志揚、 U12中華隊選手莊博淵、夢無限棒球俱樂部、臺大進修推廣學院院長謝明慧等多位師長到場同樂，也準備家庭日限定版紀念品贈送給與會者。

以「事業經營」為主軸的臺大PM學程，分成事業經營、事業經營法務，與生物科技三個碩士在職學位學程，同學在求學的兩年期間，需要利用週末假日到校上課，忙碌於工作、生活與課業的三重壓力下，往往犧牲與家人同遊同樂的時光，再加上這兩年的疫情等因素，許多親友無法經常相聚，也因此「好久不見」這句話，成為當天在現場每位PM家人們見面的第一句寒暄，也透露著對彼此的關心及思念。

這次家庭日也邀請桃園知名社區棒球隊「夢無限棒球俱樂部」的球員及家長到場一同觀賽，「夢無限棒球俱樂部」由職棒退役球員林家緯創立，其中包含他指導的「芭里國小棒球隊」。林教練感謝主辦方的邀約，讓小朋友在平時辛苦訓練之餘，也能到職棒的球場欣賞精彩的比賽。他說：「看著場上職棒選手的拼勁及專業的表現，希望能激起球員對棒球的決心。」

活動當日適逢樂天球團主題日ARMY PARTY，今年也是ARMY PARTY十周年，在五堅情激情的開球後，樂天桃猿對抗統一 7-ELEVEN 獅的比賽正式開打，「情歌天后」奶茶劉若英，久未公開露面，也在當晚登上全猿主場，獻唱多首經典歌曲，讓PM同學聽得如癡如醉，也讓與會師生們留下美好回憶。

臺大PM學生會會長楊孝妤感謝各方的協助，並且表達期許：「希望藉由這次家庭日的活動，串聯師長、校友和在校生，也邀請眷屬一同參與活動，共同凝聚PM向心力，也希望未來能吸引更多優秀的各界菁英，一起加入臺大PM學程，壯大PM家族。

Double Ridged Horn Antenna
Sort by:Select
The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable
