Hello I recently modded my sennheiser G4. what kind of sma antenna to cut do you suggest to use? I found zaxcom (straight version that is in kit 2 pieces to be cutted) for around 28$ kit. There is also audioroot swivel version for 30$ each one (60$ for 2). Remote audio miracle whip (straight version) 60$ for 2 antennas.   The zaxcom ones seems the cheaper one. Are zaxcom good? Is the swivel version of the sma connector worth for the extra price? Thanks

Buy one of these below.

 

2pcs 433 Mhz 433mhz Antenna 3dbi Sma Male Plug Connector Straight for Ham Radio|Communications Antennas| - AliExpress

 

1Pcs 710 782MHz SMA Male antenna 16CM|Connectors| - AliExpress

 

in case you need right angle. 

 

710 782MHz SMA Male Antenna Right Angle for Sony Bees Soft Antenna|Connectors| - AliExpress

 

Buy and Cut down if you wish for your bandwidth. 

 

Done. Basically an antenna is very very cheap. 

 

I have both of the antennas in your first two links. I don't recommend the ones in the first link. The wire is a solid spring wire that easily takes a permanent bent shape if bent too far. I accidentally ordered those one time instead of the ones in the second link. They are no good.

 

The antennas in the second link are good. It uses multi-strand stainless wire, is very flexible, does not kink.

 

You'll need some really good cutters to cut the wire. Even then, it takes a lot of nipping with the cutters to cut the strands. You'll ruin scissors trying to cut the stranded wire. I use  a cut off angle grinder.

 

Also notice that although it says it is for 700Mhz, the antenna is 16cm long, so it's plenty long for lower frequencies.

For a quarter wavelength whip antenna, 16 cm would be 470 MHz.  You can use the numeric length guide on  Lectrosonics.com to get a reasonable approximation for your frequencies if you want to trim to your blocks.
