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.

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.


Maybe so. Know of any good plans for something that will fit on a
pinhead?
