F-81 Barrel Connector Usage

F-81 Barrel Connector Usage


Using barrel connectors improperly can lead to signal issues for the customer and potential repair events.

Why It’s Important

Correct usage of barrels in a DISH Video system ensures that signal is still high enough quality to allow customers to enjoy their programming. Barrel connectors introduce additional failure points and DBM loss into a system, and too many splices in the signal path could interrupt the signal.

What I Need to Know

Only High Frequency Barrels (designated by a blue insert) can be used in any system, regardless of placement or receiver types

  • High Frequency Barrels can be identified by their industry standard blue center

Absolutely no barrels or splices should be used between the LNBF and the ground block/node/hub/switch.

It is always preferable to limit barrels in a system other than the wall plate.

Acceptable uses of barrel connectors:

  • Other than at the wall plate, only one barrel per signal path can be used between the node/hub/ground block/switch and receiver
    • If pre-existing cable is DISH approved and in good shape, a barrel can be used to connect to pre-existing cable
    • If pre-existing cable is not DISH approved, it cannot be used
    • If signal or DBMs are failing because of the barrel, it cannot be used
    • Barrel connections that are located outside must always be placed horizontally with drip loops, and both connectors on the barrel must be torqued to 30 inch-pounds
  • In wall plates, replace any pre-existing non-approved barrels, including low frequency barrels
    • Best practice is to re-use the customer’s pre-existing wall plate cover to ensure an aesthetic appearance
  • Create pigtail backfeed remote antennas to extend range
  • Replace the barrel connector on the Super Buddy Satellite Meter
  • If a keystone jack barrel cannot be replaced, a barrel can be used to extend the cable to the back of the receiver
