THe mast on my H-27 will be raised in a week or two. At the end of last season I was having a little problem with the VHF. Does anyone know if you can check out the coax with the mast down. Can you do it with a Ohm Meter? I don't know if the problem is with the cable, the cable ends, the antenna or the radio? If I have to replace the cable in the mast I'd like to do it with the mast on the ground. Heights give me the willies. Any advice would be helpful, Thanks,
