5.0 out of 5 stars Perfect for long range reception., June 29, 2007

By	James Rose (Marysville, WA) - See all my reviews (REAL NAME)

I bought this antenna to replace an older Radio Shack VHF/UHF combo antenna. I've made the switch to digital only OTA TV and wanted an antenna that would bring in a stronger signal from my local stations, which are 30 miles plus away. This antenna brings then in great.
Installation was a snap. The antenna comes fully assembled. All you have to do is attach it to a mast. You may need to buy a new mast if you are using a rotator with a short mast. This antenna requires about 3 1/2 feet or so of mast to attach it to a rotator, unlike the 12 inches or so that a horizontal antenna would need when used with a rotator.
One caveat - The box it comes in is HUGE. Shipping costs may be high. I purchased mine locally and had to strap it to my roof rack to get it home.

**NOTE** This review was written based on the original 4228 antenna, not the 4228HD antenna.

1.0 out of 5 stars Not the same as the earlier (excellent) CM-4228, September 3, 2009

By	Douglas B. Moran "Computer+History/Politics+D... (Palo Alto, CA USA) - See all my reviews

The predecessor CM 4228 (no "HD" suffix) was widely regarded as one of the very best antennas. A corporate change moved manufacturing from the US to China and introduced a major design change--you can find pictures on the web of the original model and see that it has a starkly different reflector grid. Consequently, disregard the (rightfully positive) reviews of more than a year ago as applying to that previous model (and some of the newer reviews may also be for the old model).

For the 4228HD, there was widespread complaints about manufacturing quality (many times in reviews comparing it to the original 4228 model). So although some may have good experience with the new model, YMMV. For something where I have to climb up on my roof, "YMMV" is almost an automatic disqualifier.

One review I saw (elsewhere) said that the 4228HD's performance is so poor that it is roughly comparable to its 2-bay sibling, which has the advantages of being cheaper (about 40%), lighter and smaller.

Design problem: _Reportedly_ the antenna generates its own interference (but I don't know how big an effect this is): The wires connecting the elements on each side to the balum are different lengths and geometries, thereby creating an antenna that is broadcasting into the intended antenna. This is so, so very basic that it is impossible for me to trust anything else in the design. Note: the _total_ length of each wire from one side to the other is the same, but the balum is connected at different points (relative to the ends) on the two wires, thereby creating the antenna effect (from a review by someone who appeared credible and that was consistent of what I remember of my course in antenna design). Background: Every wire is an antenna, both receiving and broadcasting. Where the effect is non-trivial, the standard practice is to have the two wires be the same length (same frequency response) and parallel, close together with crossovers to cancel each other out.

Design problem, balum (signal): Observation that the balum's location in the plane of the antenna results in it radiating (broadcasting) into the antenna. Aside: The balum provides the proper impedance for the coax cable downleads (conversion by induction circuit).

Design problem, balum (physical): Complaints about difficulties connecting to the balum (sealed box; terminal is not adequately fastened and rotates until it breaks). Complaints that the projected/inevitable problems with the balum (as it weathers) are not easily fixable.

Design change: The reflector screens are very different and in ways that could produce substantial differences in performance between the original and current models.

Manufacturing is also a major complaint in the (credible) reviews I found: Proper connectivity and isolation of elements is crucial to performance, but poor quality construction and assembly negates some elements.

5.0 out of 5 stars Excellant product and price, February 21, 2008

By	darc87 "darc87" (Plantation, FL United States) - See all my reviews

I bought this antenna to replace my indoor Terk. This antenna brings in all the channels I received previously as well as about 15 additional channels reaching as far as 50+ miles away. I have it mounted in my attic.

If you are going to mount this unit in your attic be advised that you need a pretty large access entry otherwise you will need to disassemble and reassemble.
