why is the Channel Master 4228HD listed as a large directional antenna, and the Antennas Direct DB8 listed as a large multi-directional antenna? They both are the same style antenna.

I'm taking this information from Solid Signal's website.

Please keep topic titles specific. See my edit.

Just because they are both multi-bow tie antennas does not meant that they are identical in design.
From the specs they obviously differ in their directional ability whcih means that there is some differnce in the spacing or angular direction between the actual bowties and the reflector. If you are trying to receive all of your channels from the same location then you definitly want the diretional model. The other model stated that it would receive signals from a 100 degree swath.

Thank you!

The 100 degree claim by the mfg is false advertising.

AntennasDirect calls the DB-2, DB-4, and DB-8 “Multi-directional antennas”. There is good justification for calling the DB-2 and DB-4 multi-directional, but the DB-8 is one of the most directional antennas you can buy. AntennasDirect is simply flat wrong about this.

The right and left dipoles are set farther apart (by 3.4 inches) on the DB-8, compared to the 4228. This results in larger minor lobes in the azimuth pattern, but it also narrows the main lobe. As a result the DB-8 is probably better at rejecting multi-path than the 4228. The major null is at about 25° for the DB-8, 30° for the 4228.

So you would say that if I needed more beam width instead of range, that I should go with the DB-4?

In general, yes. Either that or the CM 4221.

Another difference is that the 4228 works reasonably well at VHF-Hi frequencies (channels 7-13), unlike the 4221 or the DB-x models, which could mean you don't have to buy a separate VHF antenna.

I only have one VHF station, and that is about 180 degrees in the opposite direction from any of the other stations. With that said, I plan on buying a little VHF antenna to handle that one.

The 4221 actually works better in the opposite direction for some channels on VHF-hi although still not great but maybe good enough.

The 4221 & 4228 VHF reception is pretty much bi-directional, so you should be good to go for your VHF that's 180° opposite the other towers.
