For wired/ RF cable transmission to 2nd/3rd TV of the Astro Byond, basically there are 3 choices in the market:
1) The Engel brand - DigiSender2 (Multiroom AudioVisual Transmitter or high pic & sound quality AV-RF Converter from Barcelona, Spain) and this is also the one that I'm using now. It cost less than RM200 (you can bargain though for lower price), I bought from the electronic shop in Jalan Pasar - I.C. Electronics Sdn Bhd, 82, Jalan Pasar, Pudu, KL. T: 92213725 / 92218175.

2) They also sell the Taiwan made "Universal...." at less than RM70, which previously my Astro Byond Installer want to sell to me at "RM200" - that means the Installer purposely want to make quick & easy money of RM130++ by just selling this simple gadget to customers who don't know about the market price of this things. Be Aware - to those who plan to install the new Astro Byond, just a small & sincere advise only.

3) They also sell the cheaper very low signal strength DAWA av-rf converter (about RM30 or less only) which CAN NOT support for longer distance, b'cos i had tried it before with my up-stair TV (i bought from ACE before RM32.90 & return already), the sound output signal too bad just can not support at all.

Have a nice day. May everyone have a peaceful mind, positive thinking & radiate the positive energy everyday, every time from your inner self.
