Question 1

Will this work on a Mighty Mule M571 gate opener to extend the range?

Accepted Answer

It might help,  but after reviewing the mighty mule schematics, you might do better with an add in long range transmitter/receiver.

Perhaps along this line...

Question 2

Trying to pick up a weak signal from my house to another building 2500 ft away. If I have 2, 1 brdcast and 1 receive will it increase signal both ways

Accepted Answer

No.  I found it works best if the signal is above 40% (with a normal antenna) then if aimed in the right direction it could increase to 70%!  But if less than 40% to start with likely will see no gains.  If you have line of sight to the other end you will want an antenna with a very narrow focus and will need to boost the signal at both ends.

Question 3

Does this connect to the antennae of a repeater modem to then give farther reach from the original cable modem?

Accepted Answer

I used mine to connect to one of 3 antennae on a TP link router, and placed the outdoor antenna outside of a metal sided building to increase signal to an outside camera, and it did a good job.

If you are using a repeater or wireless extender, this may help with walls, etc. but will not amplify the RF signal itself.  Also, a repeater is more complex in terms of extending network coverage because most repeaters use 1/2 of the available signal to talk to the home base, cutting your "theoretical" speed in half.

If you are trying to improve wifi, look at more robust "access points" which connect by ethernet to your main home router.  Suggestions include TP link eap 225, eap 245, and much of the Ubiquiti line.

A more robust main router may also give you better coverage, depending on your current situation.

Question 4

Is the cable connected to the antenna detachable (i.e. can it be unscrewed and replaced with a better cable?) i already have a lmr-400 cable in place

Accepted Answer

Hi Sorry, the cable can't be detachable.
