ProSound Posted March 22, 2012 Report Share Posted March 22, 2012 Looking for some real world feedback from other RF Multi users is anyone set up with Lectrosonics ALP 620 powered antenna http://www.lectrosonics.com/390-ALP620/View-details.html If so I'd like some feedback on your range or feedback if there is a better powered antenna option for long runs. Also do you need any other power for the antenna or is the Rf multi supplying enough power thanks Quote Link to comment Share on other sites More sharing options...
RadoStefanov Posted March 22, 2012 Report Share Posted March 22, 2012 You can use the UFM230 right next to the antenna. Calculate the cable loss and compensate by switching the internal jumpers. The coolest thing that the PSC RF Multi SMa is the phantom powered antenna input. So no need to externally power the UFM230. Quote Link to comment Share on other sites More sharing options...
ProSound Posted March 22, 2012 Author Report Share Posted March 22, 2012 Thanks for the info RADO in if anyone else has any feedback I'D appreciate it Which antenna would be best choice ALP620 or ALP650 Quote Link to comment Share on other sites More sharing options...
RadoStefanov Posted March 22, 2012 Report Share Posted March 22, 2012 Sorry should have mentioned. No real world experience with the PSC RF MUlti Quote Link to comment Share on other sites More sharing options...
Geoff Maxwell Posted March 23, 2012 Report Share Posted March 23, 2012 I've been using one. It works great. I've experienced about a 30% increase in range although theoretically the circuitry inside the sma RF Multi should just make up for the splitting loss and not noticeably increase the gain. This was with a passive sharkfin antennas and 15' of Rg58. I just got powered sharkfins today and I will report about that later. I know this is a rather unscientific post, just my observation so far. Take it for what it's worth. Quote Link to comment Share on other sites More sharing options...
postaudio Posted January 30, 2014 Report Share Posted January 30, 2014 Can I use the PSC Multi sma to boost smqv used as an IFB? I'm having trouble getting it to work. Smqv into RF multi sma to ALP620. Thanks. Ben Quote Link to comment Share on other sites More sharing options...

" Hudson River Range ?? you could get a linear amplifier, like CBer's use... you do need to do some reading up, and a call to the manufacturers involved could change your life!

pvanstry Posted January 30, 2014 Report Share Posted January 30, 2014 Just to clarify, powered antenna are not designed to give you more range. They are designed to make up the loss of long cable run. Amplifier gain is does not mean more range. Just like a preamp, more gain means your are also bringing the background noise up with it. What makes for longer range is: Frequency selection Frequency coordination Proper antenna placement ( up high and clear line of sight ) Unity gain of component My two cents... Now let's see how many people jump at my throat... Quote Link to comment Share on other sites More sharing options...
chris_bollard Posted January 30, 2014 Report Share Posted January 30, 2014 No jumping from me. Radio frequency gain is bit like digital recording - zero is the max - after that things go from great to bad. This is part of the reason that using a remote antenna system can be more complicated than it seems at first; a little bit of research and a little bit of math. The correct selection of antenna can make or break it too. Too much gain, too much direction, too wide RF bandwidth. Quote Link to comment Share on other sites More sharing options...
