Tesla Model 3 + HAM Radio antenna v2

After few weeks of testing original Diamond configurationNR770HNMO Dualband Mobile Antenna is too tall compared to Tesla Model 3 and I ordered shorter version: Diamond NR72BNMO Dualband Mobile Antenna as you can see from photos, it’s way better from aerodynamic point of view

HAM Radio kit and Tesla Model 3 antenna

After few days of planning, I’m switching to new configuration for car and home.

Advantages of new configuration are:

  • Antenna in car is smaller (rom 38.2″ to 13.8″) and still support up to 100W output
  • New car antenna is compatible with NMO connector already in car
  • Mag Mount is heavy to keep existing antenna stable with NMO connector and it can be used home, carry around as external antenna for HAM radio Go-Kit or stored in trunk of car of need more coverage.

Here is final setup:

DIAMOND K400CNMO Trunk/Hatchback Mount

NR770HNMO Dualband Mobile Antenna

  • Bands: 2m/70cm
  • Gain dBi: 3.0/5.5
  • Watts: 200
  • Height: 38.2″
  • Mount: NMO
  • Element Phasing: 1-1/2 Lambda, 2-5/8 Lambda

Antenna is installed on right side of car connect to trunk edge via K400.

K400 0978dia2

Cable is routed as follow:

  1. Under the moving part of trunk toward front of car (photo #1)
  2. U turn back down to bottom of fixed part around the rubber insulation used to protect wiring in the truck (photo #2 and #3)
  3. Inside trunk and stick on top of it to avoid any hanging (photo #4 and #5)
  4. Move down following the back of right seat and around the seating part (photo #6, #7 and #8)
  5. Under all weather floor mat to the area between central console and front passenger seat (photo #9 and #10)

If you want to route the cable completely hidden, you will need a Diamond C110 extension cord and follow this video on how to tear down your Model 3:
