Good Evening, I have a site with a PD455-5 at 400ft that has failed me after 10 years of service. The reflected power has risen to about 10% of the forward power, and coverage is drastically reduced.
Rather than installing another PD455-5 (which will most likely fail in another 10 years due to the fact that it is top mounted without a support brace at the top), I was considering a folded dipole array. I hear that the DB420 is no longer made for the 440-450 split. Can I use a 450-470 split antenna at 443MHz without seeing any noticable performance degredation? Is it worth the extra money switching to the DB420? Also, I have considered using a PD-1151. Has anyone done any real- world comparison between the 10db PD455 and the 8db PD1151? Thanks Eric KE2D
