52 Ohm SWR meter questions.

[danoj77]

Ok so I have seen alot of cheaper SWR meters that are 52 Ohm. Now if I
understand this correctly you don't want to use something that has an
impedance that is different then the impedance of the equipment that you
are using.

EX: 50 Ohm radio <-> 52 Ohm SWR Meter <-> 50 Ohm coax.

Is the 52 Ohm's even a problem? And if it is why do they sell SWR meters
and coax cable that is rated at 52 Ohm when you need 50 Ohm?

I believe 52 Ohm is for up to 300Mhz VHF applications, The meter that is 52 Ohm may be for Higher Frequency or 10Meter 30Mhz+.....I could be wrong though....Is the 52 Ohm meter for CB @ 27Mhz....?

These meters are for 24-30 mhz and are rated at 52 Ohm.

This coax is rated at 52 Ohm.

And RG-58 coax you can buy from Radioshack is also 52 Ohm.
