Yeah, good point, they could have future proofed it with 2 LNB in cons.
Does anyone really know if VAST will go to dual polarity in the future?
I guess nothing can be certain.

quite neat how it can be a twin tuner STB, with only one LNB Input...... (basically I think it internally loops though to the second tuner.....?)

From the source;

10. Integrated silicon twin tuner (no loop through)

interesting how One LNB Input feeds to two tuners .....

The Humax looks like a nice STB....If only I could afford to buy both the UEC & the Humax to compare them...

Surely VAST will never go to dual polarity. If they ever do then all those who just upgraded their LNB's to wide-band will start whinging about the fact that they weren't told to install a dual-lnb. Politically it would be too much trouble unless there was an absolute technical necessity.

Your wide band LNB is a dual polarity LNB. I've not seen a single polarity LNB for long long time. Dual output LNB's are a different ball game altogether. If you get a dual tuner vast box (or for any other box for that matter) then you need a dual output LNB, one for each tuner to be able to use them independantly. But if using for VAST and they keep all channels on the vertical polarity then you could use the loop through feature that might be available on the dual tuner receiver internally or externally which splits the sigal for the second tuner. And then in saying that if it doesn't have that feature you could also get away with using a splittler if all channels stay on V polarity.

Obviously UEC and Humax are in the know as the can both operate with 1 LNB input.

It's no secret. All the vast channels are on the one polarity so you can split the signal internally in the recever for the second tuner.
If you were able to receive foxtel/austar as well, many channels are on hoizontal polarity so you would need an LNB with dual output so you could watch a channel on a vertical channel (vast) on one receiver and a horizontal channel on the other like foxtel.

I may have missed it but I dont see any mention of "Card Included" or need to register with vast will the Humax box come with Vast Card ?

VAST licensing requires a card that is married to the box, so we will have to assume the Humax, UEC & any other sat boxes will have a card that is married to the box.

You obviously missed it in the accessories list
"VAST (IRDETO) Card 1pc Inserted in the Smart card slot on the front panel"

Hi. With regard to the comments that VAST is on ONLY vertical polarity, what is the purpose of LNB1 in out and LNB2 in out, on the back of the new DSR 4639 twin tuner UEC recorder, if the signal can be split. Just curious.
Purely by accident, I came across the UEC advertised for $499 from Accessantennas.com.au

From the DSR 4639 manual. "Connect the Loop through F-F connector on LNB1 out to LNB 2 in. WITHOUT THIS LOOPED CONNECTION THE PVR WILL NOT FUNCTION."
It looks like UEC does it externally and Humax does it internally.

UEC have just done what all other dual tuner satellite PVR manufacturers do. VAST is unique in that only a single polarity is used, so Humax are the ones thinking outside the box and taking advantage of this.
