Re: SMA to banana binding post


 

Try cutting double or single sided FR-4 board to the required shapes.
Also, useful thicknesses of small copper sheets are available at Ace
Hardware (and likely other outlets). Keep in mind that these days, copper
is not cheap!

Good afternoon Dave,

Do you know whether those copper blanks are available anywhere that can be
bought? I have tried making some with not much success.

SMA connectors are for good two reasons: 1) Small size and 2)
Frequency response.
SMA connectors are bad for one reasonable consideration: Limited service
lifetime for mates/demates.

Banana jacks/plugs work fine at HF but not at or above 50 MHz. BNCs and
Type-N connectors are appropriate at and above 50 MHz. Top "careless"
use
of BNCs is around 1 GHz. From there on upward in frequency, either SMA
or
Type-N connectors should be used.

If you must, SO-239 / PL-259 connectors are *only* for HF use. Their
impedance is NOT controlled as are the other referenced RF connectors.
