Anyone know the specs on this LNA?

    Hi All.


    I recently brought this piece home from the dump, as well as the
    1 meter dish it was attached to. It powers up nicely on standard
    LNB at 11250 LO. 79% on a PanSat 2700, (no signal).

    The dish is in pretty decent shape too, by the way.

    I searched the net and couldn't find any specs on it anywhere. The
    only match I found was on eBay, it had no feed-horn and very little
    description.

    The faded label says;
    EchoStar
    Quality-Control Noise- 0.7 dB, Gain- 55dB.
    HEMT-1170M Ser.No.E44316370
    Made in Taiwan R.O.C.

    Is it of any practical use for FTA?, or is it just another dust collector?

    Thanks, --Kev--

    Wow... LNA... put it in a museum!

    You would need a block converter to convert the frequencies down to what the receiver can use. These Block converters are built into LNB's... (Thats what the B stands for.)

    Thanks for the response Scott.

    I guess, if anything, the feed-horn alone could possibly be useful, in the future.

    Cheers!

    Since you have the dish as well, definitely keep the feedhorn, as it will match the dish. The LNA looks like it is attached via a standard WR-75 flange to the feedhorn.

    What is the output connector?? If it's an "F": connector it probably ISN'T an LNA. F connectors are terrible at Ku freqs. 3 gigs is pushing it. Most likely it's actually an LNB. Try 10750 for LO. and do a blind scan. (H polarity to supply 18V??)
    LNA's used, usually, an "N" or SMA connector. (Never seen one with a F)

    What you posted in the picture is A single polarity Ku lnb and a Ku feedhorn. The lnb is a basic model that is good for FTA if you only need a single polarity. The feedhorn is probably matched to the reflector it was originally installed on. If you have the original reflector, you may want to look in to a different lnb if you desire both polarities from a single feedhorn.

    Thanks for the input Guys!

    I've never worked (toyed?) with one like this, and was just wandering
    if it had any use or value.

    In hindsight, I may have wasted everyone's time, since I just dug out my
    Invacom QPH-031.

    I'm sure I can fit it to the focal point of the dish, but our northern weather
    is steadily getting wintery up here. This project might have to wait 'til spring.


    Hmmm, I wander if the feed-horn will fit the Invacom?


    Thanks again Guys!

    It would fit the QPF-031 (Flange model). QPH is the integral (feed) horn model.
