Dear Group,
Somewhere I saw or heard of a inline coaxial impedance matcher. It looks like
a barrel connector but it actually has an adjustment on it for adjusting or

Instead of MOVs, how about a gas discharge tube [GDT]. OR Possibly in parallel

Dear Group,
I have a 800mhz maxtrac converted to 900mhz with the COR going out to pin 8.
The controller would like to see a High when Active. The Maxtrac is by
defaulted to low. In the menu it can be changed to high , but when I do its

Thank you for all the replies and great information.
I have another question on code selection. Other than 411 being a code used for

Also it looks like PL being preferred to DPL is not RFI specific as I have seen
