Bagaimana cara mengakali dish saya supaya gak gangguan lagi coz setiap kali ada sepeda motor yg lewat signal di rx semuanya jadi cekat cekot. Ada solusi gak yah bro?
kalo mobil lewat mungkin tanah yang bergetar yah....
kalo interferensi...dari coil mobil kan frekuensinya jauh banget....

ato mungkin pengkabelannya ada kebocoran....??
ato emang tvnya yang kena interferensi, bukat frek satelitnya??
biasanya menemukan interferensi motor pada tv hitam putih jaman dulu

kalo dgn satelit saya belum nemu kasus semacam ini,
monggo wak daeng, saya nunggu jawaban atas kasus ini yg unik.....

Itulah yg saya masih bingung bro. Apakah suara bising knalpot sepeda motor dapat mengganggu signal. Maklum rumah dekat dgn jalan raya. Ditunggu pencerahannya wak haji dan rekan2 yg lainnya. Thanks b4.

Kalo sepedamotor yang masih pake pengapian platina memang biasanya berpengaruh bro, di tempatku juga. Kalo yang CDI biasanya gak pengaruh. Mungkin bisa dicoba pake kabel coax yang serabut luar (shielding-nya) lebih bagus bro. Di salah satu stasiun relay TV terestrial saya pernah melihat dish dikelilingi sangkar strimin aluminium (seperti bahan utk mesh), untuk mengatasi semacam ini atau untuk mengatasi interferensi microwave ya ..?

Pak Haji,
Harga alat2 tsb kira2 berapa duit, soalnya di rumah saya freq 3500-3599 kena microwave interference, jadi channel2 di freq tsb signal nya kecil malah ada yang enggak keluar.
Thank's and regards

Cukup mahal Bro Boban

Ini kami pergunakan bukan untuk di rumah tapi untik Commercial Application untuk gedung2 pencakar langit, satu nya $1100.00 belum termasuk Calfornia LNB dan feed horne nya.


kalau frequency yg segitu untuk murah meriah Bro boban mengunakan sangkar faraday saja saya rasa ada di halaman sebelum nya

Pak Haji,
Makasih banyak untuk informasinya. Kalau pakai sangkar faraday kayaknya enggak memungkinkan Pak, soalnya parabola dipasang pakai tiang yang tingginya 7 meteran dari tanah.
Thank's and regards

untuk mengatasi interferensi gelombang,apabila patrabola anda di dalam kota caranya guampang>>>>

Tutup parabola anda tutup dengan rapat, dan balut dgn alumunium foil secara keseluruhan....dijamin interferensi berkurang !!!!!
