    Hi.
    My habitual shortwave listening mainly from european radio stations is slowly being phased out in favor of satellite broadcasting emissions.
    I believe it is called Digital Audio Broadcasting DAB.
    What receivers brands/vendors are on the market in USA or Europe ? How do I search for decent ones ? Any of you have one ?
    Please do not tell me I would have to pay Sirius or XM to receive them...

    Except for pay services such as Sirius/XM, I think all other DAB broadcasts are terrestrial.

    Yes, that's what I meant.

    Good ! Can you explain if yours or useable LNBs are the same ones I could find canibalizing discarded DirecTV and DishNetwork equipment usually in route to a dumpster ?
    Slowly learning the lingo, what is NA ? --> North America ? Is HH horizon-to-horizon ?

    I have a 8' Unimesh dish, am after a receiver and the LNB, plus a lot of knowledge. Can you guide me for a convenient receiver that will get Galaxy 19, 17 at 87 and 91 degrees for DVB and also DAB ?
    Are those LNBs with multiple waveguide heads at fixed angles, meant to select another satellite without need to re-orient the parabola ?
    Are those multiple heads meant for the commercial suscriber providers only, working with fixed spaced satellites ? Which would you recommend for FTA ?

    What is the highest antenna which looks like a pole with 4 thin sticks coming out if it?

    Your dish will work for KU band but might need a little modification for the LNB mount.

    I use a QPF-031 on my dish as I needed to use the original feed-horn to optimize the signal as the dish is moved but the QPH-031 or similar LNB will work nicely on a dish with 40mm clamps for most FTA stations. If you don't have a dish mover then a multiple LNB mount will work with closely spaced birds like at 87/91.

    I can't recommend a current receiver as mine are pretty old (Viewstat Xtreme/SatPros) or use internal PC DVB cards to receive stations.

    New ones are LNBFs for Ku-band. Some of these LNBFs are for circular signal, some for polarized. Find your provider's satellite on http://www.lyngsat.com If you see letters R and L next to the channel frequency, this is a circular signal. If you see H and V, this is polarizied. For FTA, you need an LNBF for polarized signal.

    People say that if your mesh is coarse (e.g. you can put a pencil through it), you won't get Ku-band on it. However, you definitely can get C-band on 8'.

    It mainly feeds an old RS PRO-2006 scanner with some frequency band/scanning mods.

    I also use it with a SDR usb receiver(RTL2832U interface IC & R820T tuner IC on USB dongle) but that's normally connected via a up-converter to a SW antenna in the attic or the FM antenna for music.
