Here is a “reprint” of a previous post about Dressler active VHF/UHF
antennas. Save your money and build or buy something else! Mike The Dressler VHF/UHF active antennas are far from impressive, especially for the price. I borrowed two of the active VHF/UHF Dresslers from the local rep (forget the model but went to 2GHz and was not the high IP3 version) and tested them on a antenna range against a Radio Shack Discone. The source antenna was a commercial 50MHz to 1GHz log periodic. I don’t have the results handy but above the mid VHF range the Dressler did a little better than the Discone but not by much, the best performance was about 5 or 6dB at 1ghz if I remember correctly, which was my upper test limit at the time. Oddly, the Discone worked about the same on VHF high band and much better in the VHF air band. What was more surprising was the Discone was better from 50MHz to 100MHz than the Dressler even though the Discone was below it’s natural cut off freq of around 100MHz. I thought something was wrong with the Dressler but both units gave the same results and the Dressler gain control was all the way up in both cases. The rep confirmed they were both working properly when returned also. Without opening the Dressler, we could only conclude the “antenna” element inside was a poor design and the internal pre-amp can only do so much with what its fed. Much better performance could be had starting with a Dressler and feeding it with a Dressler or similar pre-amp, which the local rep uses himself (what’s up with that?). If you hear of a good report from a Dressler owner, it’s probably because they have to justify the high price they paid for the thing.

There was a typo at the bottom of the post, it should read "Much better
