Re: 432MHz ATU?
A 6:1 VSWR is about 3dB Return Loss. Think of it of this way, if your feeder has 1.5dB loss (not unreasonable)
and you had no antenna at all, just an open cct, you would get
3dB Return Loss (feeder loss x 2) I suspect that whatever is left
of the connection to the yagi will not radiate that well...
Whist matching that is theoretically possible, the 'good' match would likely be very narrowband and changing frequency may make the mismatch worse, risking damage anyway.
If the mismatch changes in any way the matching cct will make it worse, risking damage.
If you must use this a 6dB power attenuator rated at the full
TX power would add 12dB to the return loss, The rig will
probably survive 15dB return loss 1.4:1 VSWR That sort of
attenuator is not common
You will hear and work even less but the rig would be reasonably safe
Best option is to pop a dipole on a long fishing pole and use
that as an antenna. It will probably work better than what is left
of your MET
I do not recommend trying to use the MET antenna until it is
