I remember Motorola had pre cut lengths for the T-1504and they were color coded With green red yellow (black or brown?) And the T 1504 instructions told you what combination to use Bob Kd6gnb

All the stuff I have is FSJ1-50A, probably should have said that in the original post but I had to make sure. Commscope says the velocity factor of that is 82% so I’ll make note of that when I do my

The 8 channel model from ICS looked nice...BUT they discontinued the effort....no further development in the foreseeable future....Price was right and all the features you could want

I would look into using mud flaps for a truck. They can be purchased everywhere, If you need to cut them in strips for the front and back then you can do that too. They also come in various

I work with many LMR sites and only once saw radio cabinets electrically isolated from the concrete floor/rebar. In this 40+ floor building rooftop, the equipment? was bonded back to a central

For smaller shoulder washers I would suggest Skycraft surplus in Orlando, they have bunches of that sort of thing and perhaps larger. As far as larger insulation instead of rubber or plywood, get

Afternoon all, Perhaps this has already been asked, but using multiple RA-35 interface cards on one rPi has anyone tried (and succeeded) at creating a multi repeater controller using allstarlink? We

?Iusuallyuseit between the repeater and the duplexer. Never tried it on the duplexer itself. But you need to know the cables velocity factor to deter a the length Sent from Yahoo Mail for iPad

I suppose you could use regular ?”. Length is tip of pin to tip of pin. Velocity factor is 86%. Assuming it is the regular 4 pack, ? wave between the bp/br, and ? to the tee. ? wave length

More of a curiosity question, has anyone built 1/4” Heliax jumpers for a Motorola T-1504 duplexer? I’ve got more 1/4” than I could ever need. What lengths would I need or what formula to

Try a bus bar insulator, you can find them in copper grounding kits or here is a random one I found on eBay. https://www.ebay.com/itm/275879709071 You will need to put a piece of all thread in to

Curious on your isolation methodology for any conductive paths to/from the rack. I’ve seen many attempt to isolate a rack, yet many other paths were available, negating the isolation. Matt

I use isolation mounts or pads. amazon com/Sorbothane-Washers-Vibration-Isolation-Absorbs/dp/B09DYXK8Z1/ You can figure out the rest of the url link.

look at rubber compressor mounting pads at Northen tools. Insulated and can support the weight. Only thing you would need to do is keep the bolt away from the sides of the hole. Stan

Like John said the transformer works. I made an adapter between the al connector to get it to a SO type.? I had several of the lines at a nice site in Spokane until firestorm burnt out the

I heard back from central steel fab; they want about $7 each with a min. order of 100. Och! $700 ?? I'll use plywood for now and keep searching. Or maybe a sheet of Plexiglas or kitchen top teflon

When I need something like this and it needs to be big enough to support something like stationary radio gear (or heavy shop equipment) I get two each rubber mallets -- Home Despot has them for $1.99
