Re: [Repeater-Builder] Re: 6-m Very Heavy Duty Antenna For Repeater Use

I just found an orphan EMS model Q2033A mobile at my door.  No cables or 
head, just the transceiver and receiver boxes.  These were used on the 
local ambulance and were full duplex, plus repeater function.  Is there 
any use for these on the ham bands?  The duplexer looks to be too wide 
banded for ham use, I remember playing with one of these duplexer's 
years ago.

Looks like I just have Micor spare parts?

that you need the regular UHF mobile manual 68-81015E70 to go along with 
it.

Oh, if the antenna is cut to ham frequencies, there is a ham discount.

Kreco has been around for a LONG time. I'd guess at least back to the 60's, 
maybe even the 50's.

Colinear antennas often test good when they are really bad. The internal 
workings can be broken right at the base, but because of a matching section, 
still shows OK. I've seen it happen on several different colinear designs. 
One of the reasons I use folded dipoles for most everything important.

Thanks...
I have never heard of Kreco antennas.
We put a DB-201 up this evening and the repeater is working just great! The 
diamond is gonna have to come down for an autopsy... I don't understand why the 
sitemaster was showing I had a good antenna when it clearly was not radiating 
anywhere useful.

Check the Kreco line of antennas.  They have a 6-m coaxial dipole that should 
perform as well as or slightly better into the valleys than the j-pole antenna. 
 You have two options the CO-41A or the CO-41H, depending upon your bank 
account and the weather severity of your site.  The shunt feed keeps away 
static on receive, and lightning away from your equipment.

 

I’m not affiliated with Kreco in any way.
