Lets say you only have one coax at your BUD. Althought it might be possible to run 18 volts to the dish and put the switch outside, is there a better solution?
Couldn't one just use a 4x1 diseqc switch and have sats listed twice? forget about 4dtv.
it would work but it would not be the most elegant solution.
here is a list of feeds and when you would use them. keep in mind its based on cost / performance. a dish that is not well tuned will perform poorly with the best feed / lnb money can buy.
single output lnbf / polarotor. used when one single cband polarity needs to be tuned at any time. can be slaved to feed multiple tuners but only one single polarity at any given time.
c / ku lnbf / corotor. used when when one single cband or ku band polarity needs to be tuned at any time. allows for ku reception on a BUD. can be slaved to feed multiple tuners but only one single cband or kuband polarity at any given time.
dual output lnbf / single orthomode feed. used when both cband polarities need to be tuned at a time. used with a multiswitch to feed multiple tuners either polarity at any time.
dual orthomode feed. used when both polarites of cband and ku band need to be tuned at the same time. also used with a multiswitch to feed multiple tuners either cband or ku band polarity at any time.
there is no real reason to use an orthomode unless you plan on distributing the signal to multiple recievers. the cost simply doesnt warrant the performance gain for most users. a bullseye 2 and 4 lnbs can set you back 600 plus dollars. a ck1 is about 50. another thing to consider is the weight of the feed assembly. a bullseye must weigh alot. i know my single orthomodes are heavy with 2 norsats. im sure most users could get by with a dual output cband lnbf and a 1m ku dish. cheaper than a bullseye setup.
looking forward to see pics of this beast when its all setup. they are monsters. haha.
crackt out,.
