Dr_DX:
Coax length from antenna to antenna switch relay box is about 30 feet. From relay box to station, another 30 feet.
I noticed something. This antenna doesn’t like to be close to other antennas. When raised, the Vector’s loop get closer to a Mosley yagi on top of the tower. The longest element tip of the yagi was about 10 feet from the Vector vertical radiating element as well. Distance from tower to Vector 4000 is 20 feet.
Marconi:
As soon as I lowered the Vector around 6 feet height, according with the analizer, bandwidth lowered to 1,460 KHz. When I rotated the yagi to have it’s longest element tip as far as it goes from the vector, bandwidth went down to 1,340 KHz.
Now the SWR meter reading is 1.0, just below from channel 1.
See the picture below.
I tested all the equipments connected between transceiver to antenna ( SWR meter, antenna tuner, amplifier, RCS - 4 Ameritron antenna switch control box, antenna relay box inside the tower, coax and jumpers included, etc) . I would like to know why I have difference in the reading. Below on the left side of the picture, the first column readings were from the SWR meter and next to it, where it says MFJ, was done with the MFJ analyzer on the same frequency of the meter. Which one is more accurate ?
The readings on the right side of the picture were done with the analyzer as well and give me different readings, different frequencies and different bandwidth. Why is that ?
