​Question:

Can I connect two or more AB4000 EW to get more gain?

 Answer:

Yes.

A maximum of three AB4000 EW antenna boosters may be used in series for very long cable runs.  A minimum amount of cable length is needed between two boosters as well as between an active, boosted antenna and antenna booster (e.g. 40 m of RG58 or 80 m of RG213).  Make sure to set the CLA-switch according to the loss of your cable.  A gain higher than necessary will worsen the performance.
