SWR of 1.75, can i do better or leave it as is?


Question

Posted

Hello All!

New to GMRS and having a blast learning and getting gear together. I recently did a install on Gen 3 Tacoma and I am getting a SWR of 1.75. Below is my build. Looking for some suggestions on how to get the SWR a bit lower, or being what it is, maybe just accept the 1.75 and call it good. Appreciate all suggestions!

 

Equipment Utilized:

Btech GMRS50-Pro - https://baofengtech.com/product/gmrs-50pro/

Midland MXTA24 NMO - https://www.amazon.com/dp/B0842B1WFS

MIdland MXTA26 Antenna - https://www.amazon.com/dp/B084BPXNC5

Ditch Light Bracket - https://www.amazon.com/dp/B0FG7P4DWY With a 3/8" Stainless Steel washer for fitment. 

Surcom Sw-102S - https://www.amazon.com/dp/B01M7QPXEY

 

NMO Mount to Ditch bracket. Recognize the antenna is not perfectly straight up and is at an angle, I'll try to figure out how to get this mount more straight up, but the way my ditch light bracket is, this may not be easily achievable.

I then ran it across the engine bay and then into the cabin through a gromet.

Both the power and NMO cable were tucked under panels.

I then created a mount for the BTECH GMRS50-PRO and connected everything behind the drivers side backseat storage.

Once BTECH releases their Mic extension, i will run the mic extension wire from the back panel to the front drivers seat, so i can control the whole radio via the BTECH mic remote. 

 

Thanks!

I also have a Gen 3 Tacoma.  I should take photos.  I mounted the mxta26 on an nmo mount attached to a bracket that mounts to the rear of the bed.  I ran the  coax under the lip of the bed and then through the drivers side pressure vent on the rear of the cab.  Then down and under the panels on the door frame to the front of the cab, across under the drivers seat and to the radio.  No holes were drilled, and the SWR is 1.01.  My bed cover is a multiple section accordion folding type made of aluminum.  I've seen a few other installations, but all required drilling holes.  While I've done that with my Jeep I'm avoiding it on my other vehicles.

Leave it as is. You'll be fine.
