Query: Simple to install - great range (1 block) - and inexpensive

I used this as the receiver for my apollo 1550 gate opener. The hot items are1 - screws line up with the mounting holes in the apollo boxApollo 1550 Single Swing Gate Operator PKG 2 - APL1550ETL + SWZOEM20, SWIL60, 2 x MLT3089, MLTA1099for the receiver2 - comes with a feedthrough to get the antenna out of the box3 - has 10 dipswitches and 2 frequencies to operate on for optimal security4 - instructions advise the installer on codes NOT to use because other mfgr's use them5 - LONG RANGE - I can open my gate from 1 block away and have it finish its cycle as I drive up6 - honest relay inside for hard contact closure (no transistor outputs)Overall for the price you can't go wrong with this remote. You can use it on garage door openers or gate openers, even use it for remote turnon of lights. Also the code system can be learned by the in-car 3-button learning remotes.No complaints whatsoever.
