Yeah,with Mesta's even StingerDSI has problems.My V1 also struggles with MultaRadar-C(K-24.100GHz) and also the problem with Mesta's and MultaRadar-C is,that RD must be positioned horizontally,but then you lose range against Multanova6,which is vertically polarized.
V1 is the king of K-band,but the funny thing with V1 is,I get better detection on Ka-34.3GHz-Multanova6FM,than on K-24.100GHz MultaRadar-C.
Anyways,there's not much you can do to inprove V1's detection on K-band Mesta's.Try tilting your V1 for few degrees down.I tried that and it works better,but not much.I would also try different mounting positions.The higher is not always the better.My V1 works best when mounted under rear view mirror,tilted around 10° downwards.
