Hey All, Well i took alot of members advice and got a Diamond Discone.What a big difference compared to yhe RS discone.Much sturdier,and alot better on VHF low band.As far as VHF air and UHF air not alot of difference.I wonder if a "N" connector input compared to a SO239 might help out in the UHFair area?I am using LMR400 with N male connectors.Thanx for all of your help and advice. Jack
