1998 Jeep Grand Cherokee Limited Edition
Tarheel M200 Antenna
Kenwood TS-480HX

Why the Tarheel antenna....
I tried lots of the different HF mobile antennas - Hustler, other brands, whip and tuners etc...and when I saw the Tarheel antenna and had the chance to talk with Robert who designed it I figured
I would give it a try....

So I bought the antenna, tilt mount, capacitance hat from Robert at the Seaside Hamfest in 2008
I installed it at the campground in Canon beach and made my first contact with Kevin VE7OVY
on 40 meters from Seaside Oregon and was suitably impressed for a temporary install.

I like the design and flexability and mounting of this antenna and the all the available options along with the quaility of the quiet movement of Pitman motor etc.

Feb.2016, After having a QSO with Jery VA3JL in Ontario on 3.710 while mobile from Ladysmith BC to Sooke with just the 6ft whip I had I noticed that the VWSR was a bit higher than normal on the Kenwood and tested it later my RigExpert I found it was 1.5:1 not bad but not what it used to be

Since I had not done anything for years to the antenna and the VSWR had been better before I decided to give it a good service and cleaning.

After the clean and polishing of all the servicable parts I retested it and it is now back to normal.
I have only done this type of cleanup twice since 2008 and I live close to the Ocean.
It has been on the back of my Jeep for over 200,000 km

Here is some spec's on our testing.

I have been consistantly able to talk (while driving) with Jery VA3JL for the last month and we figured we should do some portable testing and eventially try Mobile to Mobile  to see if we can do it over the 3200km. Stay tuned....

Just with the Capacitance Hat  - 8 ft 7in.

Capacitance Hat plus 6 ft whip - 14 ft 2 1/2 in.

Capacitance Hat plus 17 ft whip - 24 ft 2 1/2 in.

The optional quick disconnect

Capacitance Hat, quick disconnect with the 17 ft antenna


Coil without the cover and slip ring

Slip ring and coil


Front battery with 100 amp circuit breaker with manual disconnect
#4 wire used for all connections and a second battery is a 75 ah AGM battery in the rear
All grounds are using #4 including the factory battery ground

#4 ground across all joints

I added a stainless whip so I can see it on the grid line in the rear window.
this is only needed for 80 meters when the bottom of the cover is out of site.

Modified the bottom cover with a stainless bolt


Side bolt holding the antenna mount to the receiver tight and grounding it to the frame
(I also have a #4 across that connection)

The 4 pin connector is for the antenna conrol

I have also added a receiver to my utility trailer so I can still use the antenna
when towing the trailer. It still allows me to fold the antenna over and get into the rear hatch.

Tilt mount with release pin so I can open the rear hatch

Stainless release pin

Insulator for the main tube of the antenna
