Comments / Questions

COMMENT: Ti increase sensitivity due to metal garage door and aluminum backed house insulation boards. by Richard D 11/4/2014
COMMENT: Our Craftsman Garage Door opener stopped working with the remote transmitters after 4 yrs. Many sites suggest RF frequency interference is the cause. I guess a neighbor bought something using 315 MHz which is weakening the remote transmitter's signal. by Carol K 10/28/2014
QUESTION: My main interest is in getting my home link car remotes to work at longer range. Should I mount the antenna low at car level or high on the door for best results? by Ron A 8/21/2014
ANSWER: I didn't try it low, but placed it right above the door and it works great. My real issue is that it only works great when I turn off my security camera system. The cables connecting the camera seem to interfere with the antenna frequency. by Nguyen H a
ANSWER: I've mounted it just over the garage door. I'm not seeing that this antenna is delivery that much more range in general. I suggest experimenting in your garage by having someone hold the antenna in different locations. With RF signals, your environment really skews the outcome. by Rushang S a
ANSWER: hi, i use the extension to get the antena closer to the car entry at car level, I think that car level works better than going high because the signal go better thru the windshield than the roof of the car. I also recommend you to mount the antena at lease i feet away of any wall and preferently perperndicular to the wall. sorry about my grammar, I live in mexico and english is not my mother language... by roberto V a
ANSWER: I found it worked better the higher I mounted the antenna. I recently moved my antenna from the top of he garage door to the attic above the garage and can open my garage with the home link about 50', but with the remote opener I can open about 75'. It may just depend upon your terrain, my house sits lower in a cul-de-sac so going higher in the garage probably helps. by Dwayne D a
ANSWER: High will allow the antenna to pick up from a farther distance. This worked for me. by James C a
ANSWER: I installed the antenna high on the door but did not help to increase the range. by ROBERTO L a
STAFF ANSWER: This would assist that range. At the very least it would increase your range by 15 feet. Likely much further though. by Matthew O a
QUESTION: I have 3 lw3500 chamberlain openers in a metal pole barn{garage} I can only open the doors right in front of the doors, do I need 3 of these or only 1? by tim m 1/19/2014
ANSWER: You will need 3 and they do help we had the same problem with 5 of our doors by R I a
ANSWER: hi, I used this extension and works great i can open my door from 45 foot away. is really easy to install. by roberto V a
ANSWER: Need one for each opener by J O a
ANSWER: I would start with one. Then go from there. Mine works pretty well. by M I a
ANSWER: You would need one for each opener. by S E a
QUESTION: is unit simple to install myself? by charles s 12/3/2013
ANSWER: I found it quite simple to do. by J O a
ANSWER: pretty simple, good instructions by J I a
ANSWER: Yes - very easy by M A a
ANSWER: Absolutely, cable cutters and a good pair of pliers do the job well. I took my time and even used a longer cable and it took less than 20 minutes. by N I a
ANSWER: Yes. You cut one end of the cable and connect to the antenna on the door opener by twisting the wires together or use an electrical cap that is used to connect wires. The other end involves installing to a good location to receive the car open signal. by M E a
QUESTION: will this work with a craftsman opener? by jim p 8/27/2013
ANSWER: I have a Chamberlain and it works great. If you have a single strand antenna wire hanging down from your opener, this will work. Installation was easy, just follow directions. by K E a
ANSWER: The item is an antenna extender, as long as the antenna on the craftsman opener is one that hangs down you should not have a problem. by James C a
ANSWER: If the garage opener has the antenna wire that hangs down then it should. You will be connecting this coax to that wire. by Dwayne D a
ANSWER: I would think so, but I don't know. As long as the Craftsman operates in the same frequency band as the Liftmaster/Zchamberlain it should work fine. All it does is put a short antenna outside the garage that attaches to the existing antenna via a coax cable. Simple, and works great. by James W a
