Hi Alexander.

Actually I also cant imagine how to work with UmTRX without heatsink. As for extruded enclosure we discussed with you thishttp://lib.chipdip.ru/273/DOC000273341.pdfheatsink (made in Russia). In Hamburg I also discussed IP65 housing with Jean-Samuel. So, something like two parts of square pipe and all outside surfaces should be heatsink.

Best regards, Andrey Sviyazov.

Hi Andrey,

Thank you for bringing up this issue.

1. We definitely need a heat dissipating enclosure even for lab users. My

UmTRX in two channel mode heats its heatsink to 50-60C (heatsink is a blue one, which we used at 29c3). Can't image how it would work without a heatsink.

2. Please explain how do we plan to use extruded aluminium. To make sure

everyone are on the same page. Better with a drawing.

Hi all.

Sorry, I confused thread, so I repeat it here.

How about this housinghttps://www.elfa.se/elfa3~eu_en/elfa/init.do?item=50-561-49&toc=0&q=431621 for lab users ? It looks good and can easy dissipate power from UmTRX + UmSEL.

Also I like housing from Tecnoal comp http://www.tecnoal.it/. On my experience quality stable and price is not expensive. For indoor BTS 1 W we can use some of thishttp://www.tecnoal.it/heatsinks-c-profiles-series_ctg1_5_eng_2.asp, for example C180 http://www.tecnoal.it/cgi-bin/pdf_disegno/C180.pdf.

For BTS 2x10 W no idea except own design of extruded heatsink. Housing assembly should meet IP65 (waterproof) requirements.

Best regards, Andrey Sviyazov.
