Need more signal? Get a bigger dish. If you cannot get a bigger dish, then look at lnb replacement. There is not any magic in most lnbs. Some perform better than others, and there are lnbs that work correctly and lnbs that don't work correctly. Know WHY you are replacing a lnb before spending money.

Intermittent signal problems are usually not in the lnb. LNB's usually work or they don't, but there are rare exceptions. Intermittent signal loss can usually be traced to cabling or connectors. Lots of times moisture is the cause of intermittent signal loss. The least expensive thing to do is check ALL connectors first. Look for loose connections, poor fittings, or moisture inside connectors. Cables should be tested correctly when possible before replacing them.
