Interesting - yes I’ve heard people talk about the range and not needing to set gain being the pros… but I think the tx sizes and battery types would be a dealbreaker for me. Thanks for the info

How do you like the shure wireless? I’ve heard good things. Though the transmitter selection doesn’t look super appealing.

Nice to hear your perspectives. I’ve been combing through my set up, thinking of what I could improve, and that was one area I was thinking about. Was curious if using 2 passive fins would buy me any gains, but it seems like that would be negligible or minimal at best. I love the simplicity of the d-fin, though I have been thinking it could be nice to have 1 active antenna in case I need to go longer than my maximum 50ft run. One other thing I have been thinking of is filters - I have read a few diversity fin users say they’ve benefited greatly from adding passive filters to their set up (RF Venue, or PWS). The mixers I’ve talked to have added 470-608 filters and said it has improved their range noticeably. Would this potentially be because the filters have a steeper cut off on both ends of the spectrum than the antenna? I’m always a bit surprised to hear of these gains when the filters people are implementing are quite wideband already (470-608).

Revisiting this thread - I’ve been using a diversity fin and it has been fine. I’m curious if anyone has moved to 2 LPDA antennae from the d-fin and noticed an improvement in range/stability.

Ya no news but I’m definitely looking forward to its release…

So after a bit more troubleshooting, I tried a 3rd RG8X cable I have, and it’s bnc connector had a tighter fit on the BST connection than the previous 2 cables I had, and it gave me a solid antenna load signal. When I have my other 2 cables on there (they’re just 2ft jumpers), and with my fingers I put a small amount of pressure on the connection I can get a solid antenna load signal aswell. So perhaps it has to do with the fit of the connectors? Id really doubt there are anything wrong with my cables as my two 2ft RG8X jumpers have had extremely light use in the field. I use a small extension to a short whip on a little comms box I made when I need to remote my base station on commercials for more range. I haven’t noticed any issues with the flashing antenna signal in practice, but perhaps my next test can be a range test with the antenna load signal solid vs flashing. I have a feeling the difference will be negligible.

Ya I tried another rg8x cable and had the same result. I have some other cable I can try later aswell.

Had a question about the antenna load indicator on the comtek BST 75 - when I connect my RG8X cable to an external antenna (whip or sna) I have the indicator flashing, and in the manual it states the following: ANTENNA INDICATOR: Flashes when transmitter detects coaxial cable shorts and open conditions, bad antenna load. When I plug the bnc whip directly into the unit it’s solid and doesn’t indicate a bad antenna load. I will say even though the indicator is flashing with an external antenna performance seems to be normal, but I’m curious if anyone has more info about what it means by open conditions / bad antenna load, and if there’s anything I can be doing to maximize the performance.

I love my 4017b - I’m up in Vancouver so we’ve got Pacific Northwest weather of rain, cold temps, snow etc and it has never failed me.

Thanks for the post - I am definitely into the ethos of keeping things simple with passive components. When you mentioned remoting your antennae 75ft, are you referring to passive antennae? I thought I have read anything past 50ft would require compensation for signal loss. I use RG8X also for my cables. Also, are you using 2 passive LPDAs? Or are you also using the diversity fin? My wireless can be within 2 TV channels so I don’t really need a moveable filter either, but it is a form of future proofing. I guess the potential weak points in my system are the SRC receivers (not diversity reception unless operating in ratio mode as 1ch rx), and potentially the diversity fin which might not be as solid as 2 LPDAs. My cart is pretty small and mobile, so I do have the ability to easily park closer to set and do longer cable runs back to VTR or anyone that needs comms feeds. In a world where it’s helpful for us to have quick solutions to a problem immediately, being able to pop out a 100ft cable run seemed like a decent option to have in the bag also.

Update - I found one of these kicking around in my house in a bag filled with rca cables etc, hooked it up and things are sounding crystal clear! it must have been my dads antenna he originally used with the receiver. good stuff though I don’t have the “T” fully extended. I’ve kind of snaked it around the sides of my turntable and tascam 4 track that I use to play tapes on. Not perfect antenna orientation but I figure still an improvement from no antenna at all.

Thanks for the tip… yea if I was to get the DADM, which I am leaning towards - I likely wouldn’t use the power distro on it.

Hi all. I’ve been wanting to add filtering to my set up for a while and am considering a few options. Currently running a PSC RF multi with SRCs and a RF Venue diversity fin. 12ft, and 50ft cable runs for cart use only. Performance has been adequate, but I’ve seen a lot of ppl post they haven’t been super happy with this combo, and I think I could be getting more out of it if I was blocking out unwanted rf noise. I’ve been thinking of either upgrading my distro to the audio wireless DADM (built in filtering + ability to have an active antenna on a single channel, or both - unlike the rf multi) Or adding the new audio wireless rf filter/booster to my current set up ( https://www.audiowireless.co.uk/online-store/DIGITALLY-TUNED-DUAL-ANTENNA-FILTER-DT-BOOST-2-p481882216 ) Or adding an antenna with filters like the Wisycom LFA to my current system. Would be curious to hear people’s thoughts on the differences between upgrading the rf distro vs. antenna vs. simply adding a filter to the current set up…

This looks great! I’m curious, do you fully extend the antenna? It looks pretty big! Around 4.9ft when extended..

Sweet - thanks!
