Welcome to my Blog or I would rather say to my Home Page. The content here is mostly for my own use, i. e. to organize my interests/hobbies and to make it possible to recap what I have found is of interest for me. Some of it may also be of interest for you and I will be glad to share it. As you can see this Home Page has somewhat a focus on amateur radio/amateur astronomy & satellite. That is because my main hobby is or has been Astronomy,Satellite, Amateur Radio with my callsign 9W2DDA/UA1.Sometimes it is watching or digital photography.Digital Product It depends on my mood of the day. That is why the content here has a widespread focus on little here and there. My name is Dr.Mohd Anuar and I live in Cenang Beach ,Langkawi Island.

Gelombang Mikro (Microwave Band )


Gelombang Mikro adalah gelombang elektromagnet dengan frequansi super tinggi ( Super High Frequancy {SHF} ) bermula dengan 3 Ghz ( 3000 Mhz ) keatas.dengan kuasa Tx,Rx yang tinggi pergunaan bahan spt Logam akan menyebabkan tindak balas ke pada bahan tersebut.



Pada masa ini hanya syarikat komunikasi kormesial spt Maxis,Celcom,P1Max.U Mobel.RTM,TV3,TV7,TV8,TV9 sahaja yang dibenarkan mengunakan gelombang Mikro.

Apakah kelebihan bagi Rakan Amateur Radio/Amateur Radio Astronomi?
Bagaimana hendak memulakan Sistem Komunikasi Gelombang Mikro @ Microwave Band@

Bagaimana Homebrew Antenna MicroWace Band?

1.LNB ( Low Noise Block* C Band* Ku Band *)
Boleh digunakan tapi kena ada tambah Filter No


2.Helical Antenna
