Thank you.
What would happen if you were able to run 4 antenna as quad on a vehicle like that
What is the distance between the antennas? Is the co-phased harness using 50 or 75 ohm coax?
I noticed you left the doors open and standing outside. As a general rule of thumb I always get inside the vehicle and shut doors duplicating the normal operation. Maybe a little too much OCD on my part.
50ohm
Phasing coax is individual runs at a critical length into a T, then a critical length to the radio. These would also be frequency/band specific.
Motorola and GE had diagrams that showed this for lowband VHF back in the day, but the math holds for higher frequencies.
As for the led lights? Get some better non-Chinese junk and those issues go away.
