And this...
KRYDEX MOLLE Tactical Radio... https://www.amazon.com/dp/B07LG4TF37?ref=ppx_pop_mob_ap_share
To use with something like...
42.5-inch ABBREE 144/222/435Mhz... https://www.amazon.com/dp/B07X2X79B4?ref=ppx_pop_mob_ap_share
Or to make switching easier get the correct SMA to BNC male and female connectors from https://signalstuff.com/products/
And the you can twist on and off much easier to switch back and forth from the antenna relocation kit to a handheld antenna.
Don't get the VMAS or CAATail flexible antennas unless you are okay with short range and bad SWR. Better to get a flexible signalstick or Nagoya771 and weave one of those through the molle on your back.

Caatail antennas are cheaper. I see you are in the uk so it may be a wash. https://caatailantennas.com/ There are also antenna relocation cables as well. Abbree has them. https://www.amazon.com/dp/B07R7Q3PTX/ref=cm_sw_r_cp_apa_i_wiIwFbXWDX82X Hope this helps.
