Military Antenna Conversion for CB
Updated November 30, 2007
I don’t when I go under an overpass they brake off and spear the jeep that is drafting me (all most as good as a TOW missile).
OK not really, I took those photos at Garden of the Gods just down from my house, so I didn’t have the tie down assembly with me to show everybody. When it’s tied down it basically looks like a big X from behind. You will have no problem getting any where and you can transmit with it tied down.
I offered $30.00 each for three AS-1729/VRC Full Kits plus freight off of ebay. They were shipped in two boxes one for the MX-6707/VRC base unit and one for the AS-1730/VRC and the AT-1095/VRC whip. Ask the seller to over pack the whips

Two 5935714B2 Red Reflectors
Now some notes for the MX-6707 base.
1. DO NOT PAINT IT!
2. Overtightening will crack the base. Use a torque wrench 100 in. lb
Now for the fun part:
1. Take the bottom cover off the MX-6707 and look at the bottom of the unit with the coax cable/connector facing you.
2. Find the 5th tuning capacitor (small screw driver adjustment) counting from the coax cable in a counter-clockwise direction. This capacitor C8 tunes the lowest band 30-33 MHz on the antenna and will allow you to match the antenna at 27MHz.
3. You will need to have the whip attached and preferably mounted on the H1. (This is a little trickey but it can be done). If not mounted to the H1, tune the antenna on a wooden ladder, away from any large metal objects. (Like the H1)
4. Now with an SWR meter attached test to see where you are. Using the C8 adjustment (when making adjustments to C8 only use a plastic screw driver) tune it in.
5. Reassemble and retest
The tuning switch on the bottom of the MX-6707/VRC is set to 30-33 however you retune that selection to encompass 27 MHz.
