Jeremiah Sheets Posted March 31, 2015 Report Share Posted March 31, 2015 Picking up some Comteks for IFB pretty soon. I am getting Opt 7 for the bag transmitter, but probably not for client monitoring. However, since the Comtek uses the headphone wire as the antenna, if I were to put these on cameras for scratch audio where I don't want unnecessary cable lengths will I need the Opt 7 antenna? I really don't care about range benefits or occasional hits since it will be for scratch, but I'm wondering if anyone is using them on cameras without the additional antenna and if the cable causes any issues. Thanks. Quote Link to comment Share on other sites More sharing options...
Wyatt Tuzo Posted March 31, 2015 Report Share Posted March 31, 2015 I just finished a job feeding scratch to red dragons. Bongo'd a standard pr216 to the cam and fed the cam through a standard 3.5mm cable. Output in the receiver was set quite low, but it was clear. Definitely worked as a scratch track.

Joshua Anderson Posted March 31, 2015 Report Share Posted March 31, 2015 On cameras, on speakers, in cars, on clamshell monitors. In all those situations, the Comtek had a small adaptor cable and that was also it's antenna. Worked just fine. Quote Link to comment Share on other sites More sharing options...
cmassey Posted March 31, 2015 Report Share Posted March 31, 2015 I haven't looked at Comtek in quite awhile, but I don't believe you can get Opt 7 on the receivers! Quote Link to comment Share on other sites More sharing options...
Jeremiah Sheets Posted March 31, 2015 Author Report Share Posted March 31, 2015 Yes you can: http://comtek.com/pr-216-option-7/ Joshua, how long was the cable? Quote Link to comment Share on other sites More sharing options...
Joshua Anderson Posted March 31, 2015 Report Share Posted March 31, 2015 I've used various lengths on different inputs. Sometimes I've used short 4-8 inch cables. Sometimes 18-24 inch cables. But the decision was based on the connectors not the reception. Comteks are pretty robust and can definitely be used in the manner you're looking to do.

Jeremiah Sheets Posted March 31, 2015 Author Report Share Posted March 31, 2015 Okay good to know. I just don't want unnecessarily long cables strapped to the camera. Thank you for the input. Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted March 31, 2015 Report Share Posted March 31, 2015 I recall for a 216MHz system a 5/8 wave antenna is 14 inches. Our esteemed friend Larry F. posted a formula to figure this as I recall, I'd be weary of Larry's posts tomorrow though. Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted March 31, 2015 Report Share Posted March 31, 2015 Yes you can: http://comtek.com/pr-216-option-7/ I have one. I never really use it on cameras because I got ERXs not long after. I should A/B it with a regular Comtek receiver for car-car stuff. Quote Link to comment Share on other sites More sharing options...
Jeremiah Sheets Posted April 1, 2015 Author Report Share Posted April 1, 2015 14 inches isn't too long. I thought it would be longer. I seem to recall that the Opt 7 antenna system uses the chassis as a ground plane to shorten the length of the antenna and the standard system did not, but I must be mistaken.
