MClapping the 4221HD

So far I've done all the hacks except for the balun & reflector mods. On Mclapps' recommendations, I replaced the whiskers. I didn't have enough coat hangers, so I used 16 GA galvanized wire. They are 9 1/2 inches long (the stock whiskers are 8 1/8 " long with a gap of 4 3/4 ") and swept about 2 inches forward. This wire is pretty thin so it's difficult to get every whisker the same. Some ends are slightly longer than the other and the gaps between the edges of the whiskers vary from 4 1/2 to 5 inches. Despite all this, I'm getting a SNR improvement of 2 on average on each channel. I'm even getting Global on it so no need for the rabbit ears any more. SNR is also slowly increasing as the evening approaches. Two channels hover around 18 while most are 24 and above.

Mclapp suggested decreasing the gap to increase lower UHF but that will have to wait as the PVR is set. Reflector mods coming as soon as I can get out to the hardware store.

Thanks Mclapp!!!
