Heil mics (Goldline) work great with the Omni 6 with one caveat:  you have to 
have a good ground on the rig and maybe put two or three ferrite chokes on the 
mic cord where it goes into the front panel.  In other words, you may have to 
do a few things to keep rf out of your audio such as putting a line isolator on 
the feedline coming out of the rig.  I have no idea if you have to do this 
stuff with all mics or just the goldline; I had to do this with my Omni 6 and 
goldline, and I've worked guys with the same setup who had rf in their tx 
audio, didn't know it, and were running the mic into the rig which was poorly 
grounded.  My experience--hooking it up to a cold water pipe with a thin 10 
foot length of braid wasn't enough.  it has to be on a thick copper cable or 
strap going out a few feet to an 8 or 10 foot long ground rod.  If the rig is 
properly grounded and isolated, the heil mics sound excellent.  Also, the IHY 
eq. really helps a lot too.  It's something to consider if you don't mind the 
expense and operate a lot on phone.  The nice thing about the goldline is it 
has the two elements in one body so you can switch between the wide ragchew 
element and the narrow HC4 dx element by flipping a toggle switch on the mic.
