KU LNB reliability for BUD

[wildbill47]

I have not had problems with C band LNB and have 3 BUDS. KU has been a different story. My main big dish had a feed horn cover and decided to remove it as wasps lived there and considered the internal temp even though the C band LNB was not effected. Have 2 KU offset dishes and the LNB's have lasted. Naturally this is the hardest to change using a extension ladder to reach it.

The question I am asking have others had a problem with BUD KU LNB's ?
Are some of the KU LNB's being sold garbage ?

Is your BUD not particularly suited for ku use? Too large of mesh size could be an issue. A glass dish may also be not particularly suited for ku. My only experience is with an 8' Channel Master, which performed well with ku.

The front dish in AVATAR is a 8' channel master. and it was receiving KU ok and failed. When another LNB arrives will replace the one now in place. Have another KU commercial dish stored on my other property and will set it up for testing. The question I have also is with the higher summer temp if the higher freq lnb's are temperature sensitive ?

Lnb's should NOT be particularly temperature sensitive. If they drift more than a tiny bit due to extreme temps, there's something wrong with them.

Might be worth it to post what brand you had, and what's going to replace it.

spc electronics model eps-020 replacement LNB received today and installed it and working ok for now.

next time (and there will be a next time) order a norsat. I just replaced a norsat 4106 that I bought used 4 years ago. It still works but I got a deal on a better one. You can still find them on Ebay for a reasonable price.

I used 2 KU LNB's on two separate systems. One was a Houston Tracker VI on a 7.5" mesh dish & the other was a new GI 4DTV on a new 10' mesh dish. They both worked very well for me.

I have very good results using a dmx741 c/ku LNB on my 6 footer.The KU is just about as good as my 3 footer ku setup. Some here have had not so good results with using a c/ku combo Lnb though.

Thanks for the help will buy a norsat lnb next time. Have had the best results with fixed offset dishes on KU band so far.
