Incazelo emfushane:
GG-16DSB imishini ikhebula headend AW isihlungi Fixed isiteshi modulator
Isici
1. Eight Isiqophi lomsindo okokufaka, omunye RF okukhipha
2. hf kusetshenzwe nomunye Ukuguqulwa kuqinisekisa ongaphakeme aphume band iphazamise
3. MCU ukulawula ukulawula nobuningi kanye nokunemba
4. Excellent isiqophi futhi linearity yomsindo aphakeme ikhwalithi yesithombe
5. Easy operation. Zonke Misa phambi iphaneli
6. Imigodlagodla amandla imodi supply ivumela yimuphi ukusebenza emhlabeni wonke
7. PAL, NTSC futhi SECAM ozikhethela
