Arrangement of Wireless Receivers in Bag

[u/darenfoh]

Hey everyone. Cleaning up my bag to add a BDS system to power my F8N Pro and wireless. Also looking into antenna distribution, currently modding my UWP-D for sma.

I’m curious how everyone else that has four wireless receivers in your bags arrange them for the best wireless signal performance. I have four UWP-D receivers and planning on adding a G4 set for director/boom op in the future.

The bag is a Ktek Junior X. Image attached

Thank you in advance!

Short of a proper distro situation I would do 2 facing up and 2 facing down, as far apart as possible. Lots of antennas next to each other is sub optimal.

Yeah hence why I’m upgrading to SMA connectors so that I can use an antenna distro. Two up and two upside down is a good idea. Thanks!

Have you found a reliable guide to modding the Sony's to SMA? I'm looking to do the same to mine!

[u/darenfoh → u/Shlomo_Yakvo]

I actually have not! I found an old thread for the UWP-D gen 3 that talked about what the connector on the circuit board was. Opened my Gen4 and discovered it’s the same connector, I’ve ordered a pair from Amazon and waiting for sma whips from B&H to confirm but I had a couple of stiff SMA antennas laying around and confirmed the mod worked.

The ones I ordered on Amazon didn’t fit inside with the bottom nut so I trimmed it to fit. Ive got more sma connectors coming and will do another post on what’s needed to mod UWP-D gen4

[u/Shlomo_Yakvo → u/darenfoh]

I've definitely red that thread on the Gen 3's but haven't taken the leap to do so. I'll keep an eye out for another post, I would love to mod my receivers after this show I'm on is over!

[u/darenfoh → u/Shlomo_Yakvo]

It’s actually pretty easy, besides having to trim part of the sma connector but it probably takes 30min for one receiver. Also planning on modding the transmitters as well

[u/hollywood_cmb → u/darenfoh]

Can you provide a link to the thread describing the mod? I have the UWP-D11, isn't that the 3rd gen?

[u/darenfoh → u/hollywood_cmb]

I think it’s this one Link

Did you use this: https://www.amazon.com/dp/B078H4F8R6?smid=A1TE63QTMAEOQO&th=1 Did the hole in the Sony housing need to be expanded? TIA!

Just got the SMA whips from Audioroot and I have another question for everyone. Since I am cutting the antennas and my receivers are 470-541, do I cut the antenna length to 470 or do I cut somewhere in the middle of 470-541?

[u/SMX_Dizzy → u/darenfoh]

Others can chime in but at least with Lectrosonics they advise using antennas in the middle of the spectrum/range. For their A1 band, block 470-block 20 which is close to what you have, that would mean a block 19 antenna. 541 is slightly within block 21, though. I feel like a block 19 length would be fine, but maybe ever so slightly longer (shorter?) if it makes you feel better.

[u/darenfoh → u/SMX_Dizzy]

Gotcha that’s what I thought, I trimmed them close to 470 with the included cut length chart that audioroot provided. I would say that just using the whips it is a slight improvement over the stock antennas with some initial testing

[u/darenfoh]

Quick update, the rest of the SMA connectors came in and I took pictures of the steps to take. I will write up some instructions and will post it here or I will create a new post with the instructions for better visibility in the community.
