FO&A,

Which Noise Cancelling Antenna Would You Choose ?

Timewave [JPS] ANC-4 RF Noise Cancellerhttp://www.universal-radio.com/catalog/filters/0094.htmlhttp://www.ti...

MFJ-1025/1026 Noise Cancelling Enhancershttp://www.universal-radio.com/catalog/preamps/3541.htmlhttp://www.mf...

Why 'Choose' One Noise Cancelling Antenna over the other ?

Do You Use One of these Two Noise Cancelling Antennas ?

Do You Like the Noise Cancelling Antenna ?

Do You Get the ResuLts You Wanted with the Noise Cancelling Antenna ?

Would You Buy a Noise Cancelling Antenna again ?

Have You Tried a Noise Cancelling Antenna and Don't Like It ?

i want to know - iane ~ RHF

I have the ANC-4 from back in the day (JPS). It workes with my long
wire. I can't get it to work with the Wellbrook though others have
claimed to do so.- Hide quoted text -

M...Sushi,

My use/application would be with an Inverted "L" Antenna; plus
a Snake {Coax Cable} 15 Foot Vertical Antenna located outside
as the Noise {Sense} Antenna.

-I have the Timewave unit and like it very much. I use it with
-a Wellbrook ALA-330S, using an active whip as the 'sense
- antenna'. It's made a big difference for me and I've never
- regretted buying it.
-
- I've never used the MFJ unit so I can't comment on its
- effectiveness.

Addition Thoughts and Comments :

One of the things that I like about the MFJ-1025/1026
Noise Cancelling Antenna {Phasers} is the fact that they
have a SO-239 Jack for the Auxiliary {Noise} Antenna.http://www.universal-radio.com/catal.../3542rear.html

While the Timewave [JPS] ANC-4 RF Noise Canceller
uses an RCA Jack for the Noise Antenna [J1]http://www.universal-radio.com/catalog/preamps/0094dia.html

I plan on using a 15 Foot Vertical 'Snake' Antenna made
out of a single piece of Coax Cable for the Noise {Sense}
Antenna with the Noise Cancelling Combiner/Phaser.
I want this Noise {Sense} Antenna about 25 away from
the House to pick-up the local outside Noise.http://groups.google.com/group/rec.r...e30c9dfd1a8b21...

15 Feet Vertical Noise {Sense} Antenna

F=====================================P-
'o' =End Insulator for Rigging Rope
'l' = 15 Foot Vertical Antenna Element using the
Center Conductor and Insulator of the Coax Cable.
'F' = Snap-On Ferrite Bead placed where the
Antenna Element begins.
'=' = 35+ Feet of Coax Cable feed-in-line
'P-' = PL-359 Plug to connect to the Noise Cancelling
Combiner/Phaser.

FWIW - I understand that the MFJ-1025 without the little
built-in Whip {Noise} Antenna is preferred over
the MFJ-1025 that has the little built-in Whip {Noise} Antenna.

- Shouldn't the noise antenna be a vertical whip?
-

M...Sushi - Yes and No - Well May-Be-So !

Yes for a general One Whip {Vertical} Antenna "Fits" many
'possible' Noise Source Needs - When the Location and
Direction of the Noise Source is Not Known. The Whip
{Vertical} Antenna will in-fact collect all signals equally
and be very effective for most local Noise Cancelling uses.

* This would be a Two Sigma [95%] solution to the vast
majority of Home Radio Shack and/or Amateur Radio
Station needs for 'local' Noise Reduction {Cancellation}.

The Whip {Vertical} Antenna is a One-Size-Fits-All solution
for a Simple and Practical {Cost Effective} Noise Antenna
and is very easy for the End-User to use and get good results.
KISAP - Keep It Simple And Practical

When the Location and Direction of the 'local' Noise Source is
Known; or when the Noise is Severe : Then a more directional
Noise Source Antenna may be used to 'pin-point' the Source
of the Noise and Optimize the Noise Cancellation Totally and
Completely : In these cases a Dipole Antenna or Loop Antenna
can be used to better Focus in on the Noise Source and Tune
It Out; to the exclusion of other Noise Sources not in the same
direction.

* This would be a Three Sigma [99.73%] solution to the small
number of Home Radio Shack and/or Amateur Radio Station
needs for complete elimination of 'local' Noise is the objective.

The Dipole and Loop Antennas are not a One-Size-Fits-All
Solution : not simple to implement; not always practical to
use; they cost more; and are more dificult for the End-User
to use; but when done right can yield super results.
* ITALOWTGIR - It Takes A Lot Of Work To Get It Right.

Hence - Start with the Whip or Vertical Antenna and build on
your personal experience until you are satisfied with your
Noise Reduction {Cancellation} efforts to optimize your
Radio Listening and Enjoyment.
