How to Connect Multiple Dish LNBs

Updated April 17, 2017

LNBs (Low-noise blocking) units contain signal switching units that capture and direct satellite signals to main satellite antenna reflector dishes. These LNB units are primarily made with single, dual or quad switches to accommodate the use of one dish with one, two or up to four receivers, respectively. No matter how many receivers are connected to a dish via the LNB, a single LNB unit can receive signal from only one satellite at a time. In order for you to receive signals from multiple satellites to a single dish, you need to have a multi-LNB mount or a Super Mount with multiple LNB units attached to your satellite antenna.

Use the Phillips screwdriver to unscrew the lateral arm from the base of the antenna. Remove the four screws that attach the lateral arm to the base.

Attach the lateral and multi-LNB mount to the base of the antenna using the same four screws that were removed with the original lateral arm. The multi-LNB will come already attached to its lateral, therefore no attaching will be necessary. The mulit-LNB mount can hold up to six separate LNB units.

Connect the first LNB unit into the centre LNB port on the multi-LNB mount by plugging its two metal connector plugs into the two connector ports on the multi-LNB mount. Once the LNB unit is connected, each LNB port on the swivels (left and right, as well as up and down) so that you will be able to adjust the degree angle to accommodate the satellite you wish to receive with that LNB unit.

Connect the desired number of LNB units into the remaining LNB port on the multi-LNB mount, to the left and right of the centre LNB unit. The centre LNB port is the default port and must be the first port used no matter how many LNB units you place on the mount.
