I'm too often the voice of reason around my house so I'm all tapped out. I was only able to talk myself out of one for the time being because I have a couple of expensive projects I haven't completed. 

I'll be looking forward to seeing you and Paul's Tarheels in action when we can do some get togethers.

Uh, no.  Not going to try to talk you out of something to do with your Jeep.  As I pointed out before, there are lots of parts of Jeeps I don’t know anything about.  Ask me about a Land Rover and I might have an answer.  

(the answer is that the side hinged rear door on a Land Rover Disco is a PIA because it leaves you with nothing to put up and stand under when it’s raining and you’re trying to get your camera and tripod all ready before you step out into the rain to make the exposure).

I think I have decided on a Little Tarheel II and one of those triple mag mounts like Robin has.  Basically just duplicating Robin’s setup, which impressed the bejeebees out of me when she showed me how it worked.  So simple to set up.  So fast and simple in operation.  Darn good performance.  Fits in a small enough space that I don’t resent it when lugging it out to the car or back to the shack.

Re: Tarheel questions

Paul Butzi (W7PFB)
 

Howard, the antenna mounts on a 3/8-24 thread.  So any place on the Jeep where you could mount such a threaded stud, you could mount (and ground) the antenna.  Heck, you could put a stud on a plate held by suction cups and stick the suction cups to the jeep, and then just run a grounding wire to some place on the Jeep frame.  But you probably wouldn’t want the Jeep in motion with such a setup.

CB antennas commonly mount on 3/8-24 studs, so any CB antenna mount would seem to be a solution.  Looking on Amazon I see a variety of mounts for Jeeps - some that go under the spare tire mount, some seem to attach to things which I guess Jeeps have and about which I know nothing.

Out of curiosity, how do you mount the VHF/UHF antenna on the Jeep currently?  You could always pop the VHF/UHF antenna off that NMO mount and screw an NMO to 3/8 adapter, and away you go.

I was thinking about the Tarheel II but given that this unit needs to be mounted on the body causes an kerfuffle for my aluminum-bodied Jeep. Am I right to think that I would need to go to a trailer-Hitch mount and use one of the larger Tarheel antennas to use with the Jeep?

Also, can these be used "in the field" without the vehicle as a ground plane? What would need to be done to create a decent ground plane, let say in my backyard or up in the hills somewhere?

Re: Tarheel questions

W7ABD
 

A few things to consider...

The size of the tarheel antenna coil depends on where you plan to mount the antenna on your vehicle.  The bigger coils need to mounted to the frame or the lowest part of the body.  The smaller coils need to be mounted on top of the vehicle.

Getting longer whips is not a bad idea, nor is getting the capacitance hat.  As you discovered, it does effect the range of the coverage.  But the whips are easy to change in the field, so that's not a big deal.

If your planning on using a mag mount, you only need the single magnet if you plan on only using it for mobile in place (vehicle stationary).  Get the NMO type mag mount with a NMO to 3/8 x 26 adapter.

You will need a good controller for your antenna.  The basic antenna unit only comes with a rocker switch.  I purchased the Ameritron SDC 102 Controller for my antenna.  Check out the "controllers" tab on the tarheel web page to see what's available.

Pay close attention to the instructions when setting up your controller for the first time.  The smaller coil antennas have lower maximum current cut-off's than the bigger coils.

Great meeting last night, I particularly enjoyed the field day plan discussions and the discussion about Tarheel antennas.

But looking at the Tarheel website this morning I am dazzled by the array of choices.  And now I have a lot of questions and I’m hoping the Tarheel owners will put me on the straight and narrow path to Tarheel satisfaction.

I see there are some models which differ from other models by offering power handling up to 1.5KW.  I have no interest in running more than 100 watts when operating in the field, so I can exclude: Model 40, Model 100, Model 200.  (assuming there are no other reasons to pick those over the lower power equivalents).

It appears to me things boil down to two issues: coil length and whip length.  It seems to me a longer whip is to be preferred unless you want to operate while moving (I don’t plan that at this time).  Longer whip would mean higher radiation resistance so I’m guessing I want the 72” long whip, not the 32 or 36” whip.  So that rules out models: Baby, Little, Little II, am I correct?

But wait!  The models with the shorter whip cover up thru 54MHz, so they cover up thru 6m.  And the models with the longer whip cover up thru 26, 28, 30MHz, so they cover only up thru either 12m or 10m.  And I can imagine 10m and 6m being useful.  So now the shorter whip lengths suddenly look appealing.

And of course Model 300 and 400 go as low as 1.7/1.6 MHz, so they cover 160m as well.  And I currently have no antenna that will cover 160m!

What is a ham to do?

Let’s assume I’m going to follow along behind Robin, and use a big big mag mount on the roof of my car, operating only when stationary. Covering 40m and 20m is essential.  Covering 80m would be nice but probably of less value to me, as most of what I see doing is during the times when 80m is not really the best choice.  Covering 17m-10m would be handy, and I’m wondering about the 6m option.  (on the 6m thing I suspect a good option would be to just put a tuned 1/4 wave vertical on the mount and use the car as a ground plane would work well, so maybe I don’t need the Tarheel to cover 6m?)

A little guidance on this choice would be a big help.

Re: Interference

Paul Butzi (W7PFB)
 

I’ve been monitoring.

I have two separate reports:

1.  At one point while I was mobile between Redmond and Fall City, I got what sounded like DMR or DSTAR, moderate signal strength.

2.  In Carnation, HEAVY interference on 146.5, but it sounded like very loud static, with no modulation.  The interference stretched from 146.450 or so all the way up past 146.550, strongest at 146.51 or so.  As I drove from Carnation to my place, the strength of that interference faded.  I get about two bars at my house.

If someone could take a look at a panadapter when they hear the interference, well, it would be mighty nice to know how wide the different signals I heard are.

If it’s DMR or DSTAR then the bandwidth occupied is going to be narrow.  What I heard entering Carnation was really, really wide - 100KHz at least.  Or at least I could pick it up on my Kenwood D710G across a range that wide.
