USING YOUR DA25 DISCONE ANTENNA
Now we are ready for the moment of truth, the running of your discone an- tenna. Were pretty sure by now you have a place selected to install it, you can use a couple of nylon wire ties and a bit of 1” PVC pipe to fasten it into place. A fairly good “poor mans” test is to search on your scanner or radio receiver for a weak station, one that is barely breaking the threshold of your receivers sensitivity. Note your signal strength indication of the station, and proceed to disconnect your existing antenna and replace it with your DA25. If your like our many satisfied customers, your notice a significant improvement in signal quality. Try this test on several frequencies throughout the band, and find out just how poorly your original antenna was working!
TROUBLESHOOTING GUIDE
If your DA25 does not work at all,
•Correct connection of the soldered coaxial cable ends. Sometimes the ac- tion of installing the PVC pipe stresses the wire and can cause a break.
•Is that disk on the top soldered to the feed through wire? Make sure that the wire hasn’t folded under the disk and shorted by touching the ground connections somewhere.
•all solder connections
Still having trouble? While we had hoped that it wouldn’t come to this, if you are still having trouble with your DA25 here are a few additional suggestions.
Use a methodical, logical troubleshooting technique. Most problems can be solved using common sense. A
Have another set of eyes look through your work. Here at the shop we have often run into a “stone wall” of a problem only to have a fellow technician see our obvious error. It is sometimes very difficult to see your own mistake, taking a break can often solve this common problem.
Make sure that you have “checked” all the assembly steps boxes, you may have forgotten one or two of them.
Please understand that it is nearly impossible to “troubleshoot” by phone, any specific questions should be documented and sent to us by mail.
