Hi,
I am a full timer and a Ham Radio Operator. My rig is a Yaesu FT-900 AT. I curently have a Hustler mobile antenna with 10, 15, and 40 M resonators mounted on top of the ladder. I only put it up when stationary. It doesn't work very well and generates a lot of stray RF. I have looked at some others and am interested in a screwdriver type of antenna, but don't want to pay up to $600 for one. What do you all use for an antenna on HF? Any tips?

Ham Page will show you what I have done. I do NOT recommend a screwdriver ant because the coil section should be over the top of the RV. Not good with overpasses.

My nested push-up loads 80-6M and same when extended to 33' but more gain.

I used to run a Hustler-like setup on my Truck Camper. The mount was at the top of the ladder, and I kept the rig in the truck. A simple piece of coax on the ground made the connection between the two. I worked 80 -> 10m with this setup.

A screwdriver could be used in this configuration because you only use it while stationary.

Keep in mind that you need to properly RF ground the antenna/ladder to the frame of the TT/Vehicle or stake it to the ground once parked. RF grounds differ greatly from DC grounds - search around on "Ham Radio Mobile RF Grounds" and you'll get some good tutorials.

Don't forget to RF ground the rig to the chassis as well!

I've got dipoles made up for my favorite bands. At camp I just throw a line over a tree limb and pull them up and then tie off the ends. If its a short stop I run some coax out from the rig in the trailer to a HI-Q on the bumper of the truck.

I have used a similar set up - see My Yahoo! profile and click on View my photos, then look at my antenna folder.

The rig is an IC-735 with an MFJ matchbox and a 40 turn loading coil for frequencies below 7MHz.

I have a Kenwood TS-2000 in my forward head on this bath & A half model, it feeds a KAT-1 (Way too expensive marine grade antenna tuner) for 160 through 10 meters and I have a length of wire with a 2 pound weight on the end, Tie the non-weighted end of the wire to my bike rack, Stand back, Swing the weight around a few times and over the tree limb it goes. Untie from the bike rack, tie off to another item and hook to the KAT.

Plans are to put a rail along the roof of this 37' MH (minimum recommended length of wire for the KAT is 37 feet) and feed it, this will give me around 40-42 feet by the time it reaches the KAT.


Home is where I park it.
Kenwood TS-2000 housed in a 2005 Damon Intruder 377

I use a marine Shakespere 23ft vertical fed by a a SGC237 tuner and a Icom 706 MKIIG. The antenna will tune 20,40,75 laying flat on the roof.

Is your hustler a 4 or 5 BTV? Do you have it mounted on a foldover or do you assemble and mount it when you want to use it?
