Thanks !

Is it a "guess" that they tweaked it to improve the Hi VHF , even though it's supposed to be strictly UHF?

The spec for the 4228HD says it receives channels 7 thru 69 as opposed to the others that say 14 thru 69 so that might be a good guess. But then again they don't list that for the regular old 4228 so it's hard to say if it's different.

Eli- No, their new catalog formally declares the 4228HD to be for VHF-high as well as UHF. They never said that for the old antenna. The new catalog also says it is for 14-69, which is stupid. I do not know what to believe. -Ken

If you look at my graph of 4228 gain versus frequency for VHF, there are prominent dips in the graph at channels 8 and 12. I believe these are caused by the signal being retransmitted with vertical polarization. Eliminating the vertical ribs should fix this. -Ken

ken, i can't stress more thanks to your test on this antenna. After collecting feedbacks from my customers who visited Channel Master 4228HD Long-range Outdoor HDTV Antenna Review and discorvered that this new 4228 bypasses the old 4228 a lot when it comes to UHF spectum. And with you decent "lab" data... everything becomes clear and easy to understand, thanks! Good work!

cheers!

John- I acquired a 4228HD and I am evaluating it. I am not happy with it. I will be publishing my results in a few days. -Ken

Antenna Reviews?

After reading many comments here my question is... is there really a third party antenna review site that uses the same testing method to test the antenna's.

Also one of the sites linked in the above messages [link removed - editor].. in turn linked to the FCC site... but I think that the 'DOC' being linked to is out of date as it lists channels in my market area that are not even on the air and is missing others that are?..

As far as I know Ken has a hardcore "mechanical-oriented" site containing scientific data, graph stuffs.

Hi Ken! Gotta link yet for that?

Thanks

A good FAQ might be a good thing. I'm sure, no...I know there are people who believe this marketing hype. An antenna is an antenna is an antenna as far as digital or analog. Admittedly some are better performers than others, and some are constructed better than others which is a good reason for sticking with name brands. More gain is needed for longer distances. Sometimes more gain with the narrower beam width that goes with it also helps get rid of interference. The. antenna and its performance should be selected for the need/location, but there is no such thing as an antenna optimized for digital signals compared to analog. The antenna doesn't know the difference as to what kind of signal it is receiving.

No such thing?
