Jamey,
I don't think it would affect the radiation pattern of the signal from the antenna. My main concern might be whether the antenna would retain water (either rainwater or condensation). Most antennas have weep holes drilled in them to allow accumulated water to dry/drain out. If this particular antenna had them on what would be the "normal" bottom only, that would cause you concern. I'm not personally familiar with the physical aspects of this particular antenna, so I cannot say whether this would work for you or not. However, that would be my suggestion for investigation. I'm sure there are others here more familiar with the construction of the antenna, and will offer their suggestions. 73 de Mark - N9WYS _____ From: [email protected] On Behalf Of Jamey Wright I'm sure this has been covered here before but I'll ask again. I have the opportunity to place a repeater at a very good site. I can probably get an antenna at the 250 ft mark on the tower. The repeater would be in the 444.xxx range so I was looking at using either a DB408 or a DB420. The catch is that there is already a DB224 on that same mount so I was thinking I could invert my 2 choices for an antenna hang it from the bottom of the bracket. The mount is a 6 Ft sidearm on a Rohn 80 tower so it is beefy enough to handle the 2nd antenna. My question is this: Will inverting the antenna create any pattern problems or send all of my signal into the ground? Thanks for the input. Jamey Wright KD4SIY
