Exclamation CM4221HD vs. original and competitor antennas (Revised)

Code:
Gain Figures For Similar Antennas

Channel 4221    4221HD  PR-4400 SBGH

14       9.5    10.9      9.0   14.24
19      10.5    10.6     10.0   14.74
27      11.5    10.3     11.0   14.61
35      13.0    11.4     12.0   14.75
43      13.5    12.9     12.5   15.30
52      14.2    11.8     13.0   15.03
60      15.0    13.0     14.0     NA*
Notes:
  • * antenna not designed for 52 and higher
  • CM4221 is the original Channel Master 4-bay bowtie reflector (data from HDTVPrimer)
  • CM4221HD is the new Channel Master 4-bay bowtie reflector
  • PR-4400 is an 8-bay bowtie reflector made by Winegard (data from HDTVPrimer)
  • SBGH is a Single Bay Gray Hoverman Gold Standard (GH10 data from j3d)
As you can see, the two Channel Master antennas are basically matched in the 14-20 range, then the original CM4221 really pulls away into the lead. The Single Bay Gray Hoverman kicks butt!
