I just received my R75 today and I love it. What should I use as an antenna
for above thirty MHz? I tried my 60 ft. random wire but it seems to not work
very well. Any other suggestions for a new owner of an R75?

You're killing me Steve. What do you use for your scanner? I'm guessing one
of your wires?

Yes, actually, at the peak of the sunspot cycle I do indeed hook up my scanners
to the 'big' wires... reception is phenomenal... but highly directional with
regards to the direction the wires are running.

Sorry, could'nt resist. They only cover up to 60 MHz don't they? Sunspot cycle is
declining, but at any rate, you want to put up a vertical antenna cut somewhere in
that range.

When the band is open though, those long wires will receive very well, but they
are quite directional, so one needs many of them, spread out across the compass.

BRIAN,

Here is some 'specialized' VHF Antenna Information for everything
above Thrirty Mega-Hertz (30 MHz) to consider for use with your
new Icom IC-R75. (R-75 )

Guide to Scanner Antennas - by Mike Diaz
http://www.fordyce.org/scanning/scan...o/scanant.html
There have been many questions regarding how to select an antenna
for scanning. This is a Readers Digest version of antennas,
meant to give new users some idea of the different antennas
and their good and bad points.

One of the recommendations here is to mount the Scanner Antenna
20 Feet above all surfaces for the best reception.

Antenna Height - For any given Antenna Placement there is a
"Hot Spot" unique to the Height and Angular Position of the
Antenna to the your location.

So try various Mounting Heights and 'rotate' the Antenna around
the Vertical to find the best position for the reception of your
weakest signal; that you are interested in receiving.

I just received my R75 today and I love it.

What should I use as an antenna for above Thirty (30) MHz ?

I tried my 60 ft. Random Wire but it seems to not work very well.

BRIAN,

Here is a 'specific' Receive ONLY Antenna Idea to used with
your new Icom IC-R75 (R-75 )

A Vertical Omni-Directional Antenna made from a single piece
of Coax Cable for 60Mhz down to 30 MHz.

First Read this Link "Coax Cable" - by Great Yarmouth Radio Club
http://www.qsl.net/g3yrc/coax.htm


WHAT IT IS: This is a one piece Coax Cable Antenna and Lead-in-Line
for 60Mhz to 30MHz. Basically a Half-Wave-Length (1/2 WL) Vertical
Dipole Antenna Cut for 60MHz with a De-Coupling Coil at its base


CONSTRUCTION - HOW TO:
Start with a piece of your favorite Coax Cable in a 50. 75, or 100
Foot Length.
(Your Choice based on your location Requirements: Measure, Plan and
Decide.)
* The Radio End of the Coax Cable will have a PL-259 Plug Connected
to it.
* The Far-Antenna-Tip-End will have (no-connector) with the
Inner-Conductor
and Outer-Braid Soldered Together.
* Next at the Far-Antenna-Tip-End a Small ("1 to 2") Shepherds Loop
is
"Formed" and 'held-in-place' with Three to Four evenly spaced Plastic
Wire Ties.
* A Small Section (1/2" to 1") of the Coax Cable is removed at Half a
Wavelength
as measured from the Far-Antenna-Tip-End.
* A De-Coupling Coil is made of/with the Coax Cable at One Wavelength
as
measured from the Far-Antenna-Tip-End.
* The De-Coupling Coil is Six Turns of Coax Cable in small 3"-4"
Loops
that are held together by Six evenly spaced Plastic Wire Ties.
[Three to Four Clamp-On Ferrite Cores can be used instead. ]
* The "Top" Antenna Element and "Bottom" Radiator/Reflector Sections
are 'suspended' Vertically as a Unit from the Ground with the
De-Coupling
Coil at or near Ground Level.


ANTENNA MEAUSREMENTS:

STANDARD - RG-8/58/59 Type Coax Cable with a "Velocity Factor" of #
0.66.
* Half-Wave-Length (492 * .66) divided by 60 MHz equals 5.41 Feet [5
Feet 5 Inches]
* Top- Antenna Element Section = 5 Feet 5 Inches
* Gap = One Inch
* Bottom Radiator/Reflector Section = 5 Feet 5 Inches
* Six Turn De-Coupling Coil Diameter = 3.5 Inches
* Minimum Vertical Height = 11 Feet 2 Inches
* Remainder of the Coax Cable is the Lead-in-Line to the
Radio/Receiver.

ULTRA-FOAM - RG-8/58/59 Type Coax Cable with a "Velocity Factor" of #
0.80.
* Half-Wave-Length (492 * .80) divided by 60 MHz equals 6.56 Feet [6
Feet 7 Inches]
* Top- Antenna Element Section = 6 Feet 7 Inches
* Gap = One Inch
* Bottom Radiator/Reflector Section = 6 Feet 7 Inches
* Six Turn De-Coupling Coil Diameter = 4.25 Inches
* Minimum Vertical Height = 13 Feet 6 Inches
* Remainder of the Coax Cable is the Lead-in-Line to the
Radio/Receiver.


NOTE: At 30 MHz this Antenna is a Quarter-Wave-Length (1/4 WL)
