The Hitch-Viper

by

Please note that this is a "Suggested  Kit" consisting of the Military 4 foot mast poles and the Hitch-Viper. The Hitch-Viper does NOT come with these mast.  You may choose to use what ever you wish in this mount.  If you choose to go more than 10 feet above the roof of your camper or truck, then it is recommended that you install guys at the required spacing to prevent buckling of the mast. Cinder blocks will work very well in light wind. Stronger wind requires anchors driven into the ground. Note that the mast are sold at most ham-fest and are reasonable in cost. The hitch-viper will accept poles from 1" to 3" in diameter.


This is the head of the Hitch-Viper. It is fully adjustable in all directions to keep an antenna pole plumb to 90 degrees to ground reference regardless of the levelness of the camper, truck, or car it is attached to.  It also requires a 2" hitch and will not work with the light duty 1" hitch.


This will fit nicely in any 2" trailer hitch using your hitch pin to anchor it in.  I can custom make tube mounts for 1 1/2" and 2 1/2" square trailer hitches. Contact me for a price quote. Again this mount is not recommended for 1" hitches.


You may order these anchors at the time of you purchase of the Hitch-Viper.


First you have to remove your hitch mount from the square hitch receiver.


After inserting your Hitch-Viper in the receiver and installing your hitch pin to lock the Hitch-Viper in the receiver, loosen the wing nuts and back off the clamping bolt.  The Hitch-Viper will accept pole diameters from 1 to 3 inches.


In this frame you see the 360 mount that allows the mount to rotate in all directions. This unit has been in use for the last 4 years with no problems.  Again this unit like the Quadrapod is no Mercedes but a tough proven HumVee !


Insert your pole in between the V plates on the unit.  DO NOT TIGHTEN yet. Leave loose till later on when you are ready to adjust the antenna for plumb.


Now slide the pole up into the V-Plates. Next stand the pole up to the vertical position.  You may want to use a level to make sure if this is critical. Note that at this time the mast can be rotated 360 degrees in all directions and the mast will still be able to be slid in the V Clamp for adjustment to plumb.


Once the mast is in the vertical position, screw the wing nuts down to clamp the pole by hand tightly in place so the bottom of the pole is resting on the ground. DO NOT USE PLYERS etc. to do this.  These bolts will brake and do NOT need to be that tight. A added safety precaution is to drive a metal rod into the ground and lower the mast over this rod so it will not kick out from this position. It is highly recommend for heights above 30 feet above ground that guying the mast near the mid or top point for protection from wind is highly recommended. Securely screw down all wing nuts and bolts to lock the Hitch-Viper in place.


This shows how  the pivot point will allow you it to stand the mast straight up even if the vehicle is not on level ground. This is of my own design allowing movement in all planes or directions and is the only one of it's kind to my knowledge.  They are fully machined and built with care by me and welded in house with a mig welder.  These units should last many years with very little maintenance due to the simplistic design.


Now you can start adding your mast poles to the desired height you wish and then install any antenna you wish.  Remember that the poles must be able to support the weight of the antenna. If you choose to go real high up, then you will need to order a couple of rope guy rings to keep the pole from buckling in the middle should a wind come up. Free standing is suggested at 20 feet max from the ground.


As with the Quadrapod, simply walk your poles up with the antenna and coax attached. In this case out Great American Flag is to be on top of the mast at 30 feet. The Quadrapod is in the back ground with the guy straps in place to prevent turning over.  I simply removed the mast from the Quadrapod and moved it to the Hitch-Viper for this show and tell. A number of people have use the Hitch- Viper for the center pole and 2 Quadrapods for the ends of the various wire antennas in order to keep the the antennas above the head height of tall people to prevent injury especially when set up at Public Events, JOTA or Field Day.



Standing up the pole.  Note how the pivot point is both back to front and left to right to insure a vertical position of an antenna. Once vertical the mast then can be allowed to slide down a few inches to rest on the ground or a rod driven into the ground to prevent kick out.  After in position then the locking screws are tighten down to secure the antenna mast and pivot in place.



In this picture you need to tighten down all locking bolts to insure that the mount does
not rotate and the antenna falls.  No wrench is needed, but be sure to check all point of the clamp and tighten with a hammer or even a rock on the main pivot bolt cross pieces.  Do not hammer on the wing nuts clamping the long plate bolts.  This is not necessary and will break the clamp bolts.



This will support as you see it a small 2 meter and or 440 beam but no rotor. Should you wish to use a rotor, you will need a 3 point guy on it using cinder blocks or better yet the guy anchors.  The length of the Hitch-Viper is such that the tail gate of a pickup may be opened at will without lowering the antenna. This allows one to operate from the tailgate of the truck if desired. Shorter or even longer lengths for the Hitch-Viper are available upon request.  Contact me for a quote. This unit can be left in the bed of your truck for setup anywhere - any time and weather will not hurt it.. 

The Hitch-Viper has to be removed when the vehicle is placed in motion on the road.  It can be move around an area with out removal provided you have someone holding the mast up vertical and walking beside the mast to prevent falling or injury to others although this is not recommended. 

JUST DON'T DRIVE YOUR VEHICLE WITH THE HITCH-VIPER MOUNTED
 IN THE RECEIVER ON THE BACK END OF YOUR VEHICLE.
It becomes a battering ram and cops will get kinda ill !
