Well, I got no responses to this, so I'm guessing that nobody had any experience with them. So I'll post my thoughts on the Hustler Mobile HF system on 11 meters.
First of all the construction of the antenna seems to be rather stout. I have an issue with the way the resonator mounts to the mast however.
The resonator bottoms out on the mast threads. I would prefer that the resonator mounted flush with the mast.
This thing is tall. I got this new job and this new truck and got excited about the possibility of easily mounting a tall antenna on the truck. With the mast, resonator, whip, and mount, the antenna sits at 13'2" when mounted on my mirror and SWR matched.
I had begun this project with alot of frustration. I ordered the MO-3 mast. Solid non folding, and the RM-11S resonator from HRO. I got an email informing me that the RM-11S was out of stock, so I took a refund and the RM-11 resonator. The lower power handling of the smaller resonator didn't concern me, but the narrower bandwidth did.
After receiving the antenna parts, I flew to Omaha to pick up the truck and was informed that the maximum height for these trucks was 11'6" due to customer requirements. I called HRO and with shipping and the price difference for the foldable mast, I was looking at another $25. I found a folding mount at a truck stop for $10
I thought I would give it a try. The antenna folds nicely at mirror level, and will keep the customer happy.
When I first installed the antenna, I reached for my bag containing my cheap but effective SWR meter and my multimeter. It's nowhere to be found. Gone. Not in the truck, not at home. So I check it with the radio meter and peg the meter from 26Mhz to 29.999Mhz. Time to stop messing with it.
I drove to my uncles place, on my way to pick up a load, and borrowed his multimeter to check for shorts. No shorts, at least something was going right.
I folded the antenna over loosened the two set screws for the whip and slid the whip in to the half way mark. Calibrated the meter and checked again. My 2510 meter showed nothing on channel 1 or 40.
You got to be kidding right? One adjustment and it's flat, I don't believe it. Left my uncles place and stopped at a truck stop. Borrowed a rat shack SWR meter. It shows 1.1:1 across the 40 channels climbing to 1.5:1 at 27.5Mhz. I am happy with that.
Called out on 38lsb from Billings, MT and first response I got was from Atlanta, GA. So it is getting out.
On the receive side, I am hearing stations across the country today, some of them I recognize, they are booming in today compared to where I heard them before with just a 5 foot Firestick.
Overall for my first day running this antenna I am happy with it.
P.S. don't mind the dirty truck. It's brand new and not supposed to be washed until 45 days after delivery.
