hi Arthur:

thanks, I ordered antenna mast, nut and insulator for about $52 plus
shipping from Majestic Honda. I just installed it and the antenna is
working fine now. I thought the motor is broken after I opened the antenna
motor unit to take out the broken cable, but later I realized that I have
to close the trunk in order to operate the antenna. The instruction didn't
mention that. I think Accord automatically shutdown the power for antenna
motor if trunk is opened.

thanks again
