I have a SDS200 installed in the car, with a HP RF Limiter between the permanent mounted (hole drilled) NMO150/450/758 antenna (swept here by mmckenna). I remember it did pick up some CB, though that traffic is almost nothing.
I'm diving into adding HF+6 to the car at 10W, and the conclusion I've come to is I have no real good options except to add a screwdriver antenna, which would end up being 3' from the scanner antenna.
Question 1, with the RF limiter inline, do I need to add a HPF?
Question 2, I've been looking, and I need VHF high to be picked up still, so I looked at mini-circuits and there are two that might work for my situation:
Are there any better options?
