I'm thinking about buying a used Lectrosonics m187 transmitter and cr187 receiver. The transmitter uses the mic cable as an antenna (dipole?) and I'm wondering if anyone has an opinion on this type of antenna configuration. Is it better/worse than the type of antenna I'm used to using where you attach a threaded antenna on the transmitter bottom?
Thanks, Steve. I think I should be OK. Only using for corporate video headshots and light interviews, so hopefully sweating won't be an issue, so sounds like this should be suitable. Can't beat it for the price.
One other question, I'll need to get an antenna for the receiver (it doesn't come with one). I have a couple foot long rubber duckies and a couple foot long wire antenna (they're rigid wires with a small circular loop at the end). Are antennae universal, in other words, can I use the antenna I have from my other Lectro unit on this one?
Antennas are typically cut to a length proportional to their frequency (actually wavelength). 1/4 wavelength is a typical length for a whip antenna like that. Suggest researching the documentation and/or contacting the manufacturer. If you use an antenna that is very much different than the optimal length, it will significantly reduce the reliable operating range. I wouldn't recommend just connecting any old random antenna.
