RE: [Repeater-Builder] db224 Down Tilt

2010-01-24 Thread Jeff DePolo

I've never seen one for a DB224, though I have seen them for a DB408 (4-bay
UHF) with 9 degrees of downtilt.  

A DB224 has a pretty fat 16 degree beamwidth in the elevation pattern.  You
sure you really need downtilt?  If your problem is dead spots extremely
close to the base of the mountain/tower/building where the repeater antenna
is perched, more than likely what you need is null fill, not downtilt.

 Subject: [Repeater-Builder] db224 Down Tilt
 
   
 
 Is it possible to order a new db224 with a down tilt harness? 
 I've only found one other open dipole with down tilt and at 
 three times the price. I run a high elevation repeater and we 
 need to contour down below us.
