I need coax jumpers (thin), for my VHF/UHF amps.  LMR 240 and generic seems
to be the cable I need.  Tired of using RG8 that is hard to bend.    New
shack is cramped.  Any suggestions?  I found these so far.

About $16 for 3 feet.      PL-259 both ends.

2.8db @ 150MHz

5.2db @ 450MHz

PL-259 both ends.  American built (in this case it costs more for less)

 

3.6dB @ 150MHz/0.55kW


6.3dB @ 450MHz/0.31kW


 

Look at the difference in specs.  Given these two, it's a no brainer to get
the Cable Experts one.  If you find other sources, let me know and I'll
look.    Got any old used ones you no longer need?  I need a total of 6
jumpers in range of 1.5 ft to 3 ft.  2 with PL-259 on both end.  4 with
PL-259 on one end and N on other end.
