I concur with mmckenna.
I used LMR 400 (not ultraflex) from my antennas to my "radio room", then I used LMR 240 ultra flex jumpers to my receivers. By the way, in most cases, I used N Type connectors on my LMR400 cable - on the radio room side. Like mmckenna said, use the connector that matches your antenna on the antenna side of the LMR400. I also avoided adapters.
Then I ran that into a double female N barrel connector:

And finally a jumper LMR240 ultraflex with a N male on one end an BNC male on the other end. Sometimes my BNC male was a right angle BNC male.
Cable Type: LMR240 Ultra Flex. Connector 1: BNC MALE. Connector 2: N MALE. Type: Ultra Flex.

They are expensive, but you can also go to usacoax.com and have custom cables made with just about any connector. For the LMR400 I bought the bulk cable, the connectors and crimpers and put the connectors on the LMR400 myself, but if I had it do all over again, I would just pay to get the 50ft LMR400 with desired connectors on it already. Good crimpers are expensive and if you don't use them much, it isn't worth it.
You can also get different patch cables to match your receiver, i.e. N type to SMA, N type to PL259, depending on the connector on your radio.
