Looks like I have to replace my Wineguard antenna as the plastic bracket on the antenna unit itself is cracked where it attaches to the two square aluminum support arms. (Very cheap design). I could just replace the antenna unit or another option is to convert from a Windguard to a "Jack" antenna. Supposedly the Jacks head will attach directly to the Wineguard support arms with an aluminum mounting bracket. Does anyone have any opinions on the reception of the Jacks versus the Wineguard or has anyone ever made such a conversion? As I said, I could simply buy a new Wineguard head but in my opinion the design of the plastic attachment bracket is destine for repeated failure. Any opinions out there?
