Just bought a universal antenna from walmart. It states it would be compatible for all cars. Yeah right. I removed the stock antenna( im replacing it because the mast broke off) instructions told me to cut off the stock antenna assembly and just attach the universal one. Wasnt that simple the coxial cable was more larger than the universal adapter thus it wouldnt fit. And the inside of the fender area just has no space for the universal antenna. Long story short I have a broken universal antenna and a cut radio cable behind my fender. What would be a good replacement?
