  1. Recommendation for an useful radio-astronomy book where i can find all necessary informations relating to the construction of an antenna that can read signals from non-organic hydrogen!!!
  2. Thy,a lot,i saw many examples of feed horns,each was equally good,it is important that alu sheet must be galvanized.I saw one guy made it from a single PVC tube and alu tape which was wrapped inside the tube.But alu coffee can,or proper alu sheet is efficient.I will stick to the right thing... Ckecked your Bias Tee by using pic,i hope it is the same you bought...It is quite expensive,i hope there is a bit cheaper one and also efficient...I can't do anything without it at all... https://www.ebay.co.uk/itm/Axing-TZU-15-02-Remote-Power-Inserter-max-1-A-for-Satellite-CATV-terrestrial-5/362431982015?epid=1719961720&hash=item5462a129bf:g:XF0AAOSwPXdblFAn:rk:1:pf:1&frcectupt=true
  3. Hello world,a phraze i saw in "Watch dogs" game,that i like to use every time when i am going to meet a new people. Since 2011 astronomy and my interesting in celestial objects,lately cosmology and radio-astronomy as well,has become my primary hoby which growns almost into an pure passion.But i won't be that arrogant and i should to be modest and say to my self first "i am lacking on knowledge",because astronomy,astrophysics and cosmology are constantly complemented by new information by time.What more can i say....I am Zijad from Sarajevo/Bosnia and Herzegovina,where astronomy is an relatively marginal scientific branch,unknown to the wider masses here.Despite that fact i am not even pesimistic,and i am sure that one day astronomy will be very popular in my country,but at first we need to offer to people our best of knowledge we posses to bring people closer to this beautiful scientific stuff which popularity constantly growing by time. Also i am working on my greatest project to date,trying to catalogue as much as possible all known stars from all constellations,to to very details.It would be an huge catalog which consists over several hundreds of known stars of various magnitudes.I hope it will be finished untill 2022.But to be honest it will be printed in only single copy,for own collection. Best regards astro bros....
  4. Domestic vendors has no any of necessary parts which are needed for assembling in their stores.Therefore,i've just made my first offer via Ebay.Starting with two In Line Amplifiers. Nice case for internal parts.Ok,which "feed" dimensions are best for 1m dish?And,you did not emphasized earlier anything about Bias tee,or i just missed to read about it! @Carl Reade
  5. Yes i was thinking about it last night,i have on my mind to visit an local tinsmith,he could make me an proper antenna feeder,i just need right "feed" measurements for 1m dish.If you any better idea just drop it.I know i can construct it for a less money,but professional touch could be a better and long lasting solution...
  6. @Carl Reade That vendor does not ship to Bosnia and Herzegovina,but i think this one could be equally good as previous.....I mean it is same. https://www.ebay.co.uk/p/LNA-50-4000-MHz-RF-Low-Noise-Amplifier-Signal-Receiver-Spf5189-NF-0-6db-Ark/12006537045?iid=163253465136&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D20160323102634%26meid%3De686c2d8f0d34eed957b3d6418a88df1%26pid%3D100623%26rk%3D2%26rkt%3D6%26sd%3D263793459193%26itm%3D163253465136&_trksid=p2047675.c100623.m-1 But,i can also check in the local shop that also selling satelite and cable equipements.
  7. @Carl Reade Carl I would like to thx for all that suggestions....Link you gave me is a very usefull )going to add them on favs),i see that guy used can instead LNB,but is it possible to keep LNB on its place without changing it,if not ,let me know.I can get 55 x 60 dish for completely free from an guy,he offered it to me....So,with that i can be on the horse,therefore,i will save some extra money. I can't wait to see your whole assembly proccess.Pls,do not forget to display it.I am trully appreciate your help. PS:I want also to ask you about that Hydrogen 21 filter (LNA),whether the seller is reliable?Or is there any alternative i can buy on Ebay?
  8. @Carl Reade As you recommended,i hope i picked it properly.... I know i need a dish to nearly 1 meter (diameter),nothing bellow 96 cm... 1.LNA https://www.ebay.com/itm/0-1-2000MH-z-RF-Wideband-Amplifier-30dB-low-noise-LNA-Broadband-Module-Receiver/311841967599?hash=item489b3acdef:g:KrwAAOSwuLZY57ZS:rk:1:pf:0 2.Satelite line amplifier 20db https://www.ebay.com/itm/Satellite-20dB-In-line-Amplifier-950-2150MHZ-Signal-Booster-For-Antenna-AE/382605486101?hash=item5915106815:m:mU717aqYcmk_Qtp-xdJxoQw:rk:1:pf:0 3.I need your sugesstion about these Filters in line.... 4.Power suply will not be a problem... 5.SDR donngle... https://www.amazon.com/dp/B0129EBDS2/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=rsv0f-20&linkId=9806dfa291f74f7cdb49e2cfbe3d34eb or even this one..... https://www.amazon.com/dp/B011HVUEME/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=rsv0f-20&linkId=983e9b382e58ce311dbc03b00457d4c1 And best possible guide to assemble all tgoether... I hope i am not too boring with endless questions...
  9. Hydrogen,strictly... I just need useful details,so i am not wandering around.It could be easier for me to finaly start ordering all neccesary parts.
  10. Hy,i am looking to invest some money to construct my first radio telescope.And i am very serious with this!!!!! I found many examples outhere from several sources,but still condused which is better for beginner like me.I just want to make things easier,bit complicated,to get into this stuff. example....... https://www.haystack.mit.edu/edu/pcr/vsrt-ret/VSRT_Assembly_Summer2009.pdf Pro and cons with this setup,and is there any simplier or bettre solution??I will take into account all suggestions.. All i need i just best solution with dish,which parts i need to assebmle into the one functional device i am planning to use. Any help is welcome.
