I'd like to add a question to this post, if I may. My EF-SWL is on
backorder. I have heard that there are two different reception
characteristics depending on horizontal or sloping installation. Can
anyone tell what the suggested angle of the sloper installation is,
and what the direction of best reception is in each? Thanks!

There are antenna patterns included with the manual showing patterns for
sloper and horizontal vs. frequency. Because the patterns change with
frequency, there is no optimal slope angle. If you have a particular
installation in mind, E-Mail us and we'll genrate plots vs. frequency
We're shipping backorders as fast as we can- 45+ will go out this week.
As a side not, these antennas use #14 polyethylene coated Flex Weave-
arguably the most expensive antenna wire available- 130 starnds of #38 from
memory, then a high density poly jacket ( not vinyl as is usually
encountered) is extruded over the wire. The binocular core 9:1 transformer
is housed in a custom molded ABS ( UV stable) box with all stainless
hardware and silver/teflon UHF connector. Both secondary and primary
transformer grounds are available separately for optimal grounding.

Setting-Up the Ground Connection

The general 'directivity' of a Sloper is toward the Bottom-End.

Doing-the-Math on "Sloper" Antenna Installation of the Par EF-SWL
Antenna with an Antenna Wire Element that is 45 Feet long.

If the Bottom-Mounting-Point is at or near Ground Level:

* When a Sloper is Rigged at 45 Degrees then the
Top-Mounting-Point would be set at 32 Feet.
The Ground "Foot-Print" of the Sloper would be 32 Feet.

* When a Sloper is Rigged at 30 Degrees then the
Top-Mounting-Point would be set at 23 Feet.
The Ground "Foot-Print" of the Sloper would be 39 Feet.

In either case, if you 'elevate' the Bottom-Mounting-Point by X Feet
then the Top-Mounting-Point needs to be 'elevated' by X Feet.

The Par EF-SWL Antenna can be Rigged as a "Sloper" using a Top
or Bottom Feed-Point.

* The Bottom-Feed-Point allows for the 'placement' of an 8 Foot
Ground Rod at the Bottom-Feed-Point and by leaving about a Foot
of the Ground Rod above ground level the Par's Matching Transformer
can be Mounted directly on the Ground Rod. If conditions are
right; you can run the Coax Cable Feed-in-Line alone the Ground
directly under the Antenna Wire Element as a Ground Reflector.

* The Top-Feed-Point allows for the 'placement' of an 8 Foot
Ground Rod at the 'base' of the Top-Feed-Point. Run/Route the
Ground Wire Straight UP to the Top-Feed-Point and connect it to
the Par's Matching Transformer. If conditions are right; you
can also run a a Ground Reflector Wire directly under the Antenna
Wire Element. NOTE: If you can not install a Ground Rod at
the base of the Sloper's Top-Feed-Point and are relying on the
Coax Cable Feed-in-Line as your Ground 'connection'; then try
running/routing the Coax Cable Straight UP from the Ground to
the Top-Feed-Point.

Thanks!!! This helps me make location plans for when the antenna arrives.

for those of you who want this antenna but can't afford its over $50
price. RFJUNKIE on ebay has his own version for $22 !!!

his products work !

I agree. I use the RF-SWL with both my Drake R8B and my Icom R75.
I use it indoors as I live on the forst floor of a brick
apartment building where managment is always going aroung checking for
anythin outaide that isn't permitted.
I used sekf adhesive picture hools aroun the 2 outside walls and ran
the antenna around them, then back a short distance to the end wher I
used a regular hook for the can.
For grounding I used ordinary tan (to match the paint on the walls)
dopper
stranded hookup wire to a cold water pipe using an automotive hose
clamp.

Tgis setup is very quiet and works terrific.

Complements to Par for a very nice product.

you agree with what ???????

if you haven't tried the other product how do you know its not better ?????

that is the most stupid thing I have ever heard.


have you heard the terms:

ripoff
great value
piece of junk



you don't always get what you pay for !!!!!

look at many american cars !!!!
