RE: [Repeater-Builder] Re: DB224 "Loop" Lengths for 145.110 Mhz?

[Mathew Quaife]

I will have to agree with Dean on this one.  I took the DB-224 as it sat with the changed elements, old 150-160 harness, put the antenna up 60’ in the air, and it was out performed by 20 to 25 miles against a Diamond  XNH-510 Dual Band Antenna.  Impedance if I remember right was somewhere near the 80’s.  VSWR was right about 1.6:1.  And I agree with the mag mounts, the family thinks I am nuts for popping two holes right in the truck of my Cadillac.  When I get done with the car, for $11.00 a piece I’ll just leave the mounts and cut the coax.     Mathew     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, January 24, 2005 5:44 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: DB224 "Loop" Lengths for 145.110 Mhz?   Hello All, Do not count on this info being right. The top needs to be right from the top of the mast support pipe to the 1st dipole and then center to center on each after. If the support pipe is not long enough get a longer one. They come in different lengths one for 222 is shorter then one for 174 and one for 144 is longer then the support pile for 174. I have noted this in our warehouse when they are side by side. Here at work we take a DB-224 in band and tune it to the frequency need  by the user and everything on this antenna matters so be mindful when you tune or covert one. Matthew is correct after you change the dipoles for Ham uses from the 150 range you must change the harness to make it play right. Oh it will work but not as well as it could. Like someone said this morning on the list. There are people who use mag mounts and tell you how great they work. BIG GRIN! Dean Westbrook, EE,PE Cook Towers, INC.     Yahoo!
