Are there plans on the web for using garage door systems to operate gates? Remember, the gate may have to be modified to work with the garage door opener. One can find similar systems at Home Improvement centers in the $500 - $1,000 range, depending upon the gate style. From a security viewpoint this would be the way to go. Using the company frequency even with a custom TT would compromise the integrity of the facility since an "enemy" could record and analyze the TT sequence.

Given the cost of the new mikes and special equipment at the electric gates, etc, it would be a lot cheaper to go with the garage door opener style system. Maybe I'll work up an estimate of what they might spent for both systems and the economics might help them make a better choice. joe -------------- Original message ---------------------- From: "Dick" <[EMAIL PROTECTED]> > They already own the radios, they already have the freq, no new in-vehicle > gear > needed and no training to speak of. > > Dick > > ----- Original Message ----- > From: [EMAIL PROTECTED] > To: [email protected] > Sent: 26 May, 2007 15:22 > Subject: Re: [Repeater-Builder] OT: Need to find a product to develop > goodwill at a tower site(s) > > > They rejected this idea.
