i have an IDX CamWave CW5-HD wireless transmitter here. V-Lok and SDI. $1200
it is used and has some wear but works great. it has been my backup for a few years. just time to slim down.
the unit works great, locks signal quickly (in my experience). my test today gave me about 50' with two double-thick brick walls. it started to scramble at about 60' after the third brick wall. receiver has lots of hard-side vel-cro.
let me know if you have any questions. i am located in los angeles (though ill be in new york this week and can bring it with me if you contact me before tuesday 4a pacific). happy to ship anywhere. $1200 pretty much priced to sell. let me know if you are interested in a trade. ive also got lots of IDX batteries and charger (with case), a 7" hdmi marshall monitor, and a nanoflash if you need a bunch of stuff.
