Question to those who may have used one - Do inline isolators work
well on RX? Such as those sold by Radioworks?
Thanks,

BpnJ : Why are you considering an Inline Isolator ?
1st and "Inline Isolator" requires inserting something
'in-the-line' in the Antenna to Radio Feed-in-Line.
2nd the "Inline Isolator" requires two more Connections
{Joints} in the Antenna to Radio Feed-in-Line.
*If* Your Antenna to Radio Feed-in-Line is less that
150 Feet : Then most likely you do not need an
"Inline Isolator".
*If* Your Antenna to Radio Feed-in-Line is on-the-ground
or buried-under-the-ground a few inches : Then most
likely you do not need an "Inline Isolator".
However : If your Antenna to Radio Feed-in-Line is
In-the-Air {Overhead} from Tree to House : Then may
be you could use and "Inline Isolator" at the House
entry-point with another Grounding Point/Ground Rod.

We have all most likely done it the wrong way more than once . . .http://groups.google.com/group/rec.r...5cc467b35a70d5

Short answer - I am getting desperate over the noise level here.
Grasping at straws.
The fellow I spoke to who makes these things said they are best used
as close to the receiver input as possible.
You gotta build a loop.
