Hey Ken,

Any comments about this antenna versus a CM4228?

I have the DB2, which has 1/4 the surface area of the DB8, and am very happy with it's performance-if the antenna is pointed at the transmitter. I get a 90+ signal from towers that are 35mi. away, and almost no signal from a tower that is 4 mi. away but in the opposite direction. That's fine with me because I have all the HD towers in the same direction(3), and that one channel I don't get is not HD anyway. I am sure the DB8 would work great at long distances-but it probably isn't "bi-directional" without a rotor.

Now if they could have just made it so you could flip half the elements to look in the opposite direction, then........

Cool!

But how do you think it compares to a CM4228?

Thanks

I will throw out that the DB8 appears to have more gain in the upper channels but below about 40 UHF they appear to be roughly the same.

Richard- As the net gain graph shows, the DB-8 performs better on the high channels, but the CM4228 performs better on the low channels. The DB-8 costs more, while the 4228 is heavier but has some VHF reception that might be useful. Apart from these things, I consider them interchangeable. -Ken
