First, I just joined the forum and wanted to say hello.
Second, I just purchased and installed a Midland MXT575, here are the details/questions:
I just installed my MXT575, using a shortened 12' midland (MTXA24) nmo cable(by CoolTech) attached to a Midland MXTA26 antenna. I have it mounted to a CoolTech stainless steel nmo mount next to the am/fm antenna on the passenger side hood cowl panel of my JT(Jeep Gladiator). I did run the power and antenna cables next to each other(??) and zip tied them to the vehicles wiring harness(??).... When testing, on channel 01(low power), I had SWR readings of 1.01 / FW-W 2.94 / RW-W .000 , but when I tested on channel 20(high power) I had SWR readings of 1.62 / FW-W 27 / RW-W 1.51. - First, I do not understand why there is a difference in SWR ? I am happy with the readings, but feel @ High power they need to be better and achieve at least 1:5:1 or below. Secondly why is the output wattage so low for a 50 Watt radio ? I have seen this radio tested on YouTube several times and on low power it was 5.00+ watts and on high 49.00+ watts. I thought I might need to test into a dummy load for an accurate test, but during the YouTube test, the readings were the same whether testing into the antenna or a dummy load. I would prefer not to have to spend the $ on a dummy load if it is not needed. I did just read that Midland GMRS antennas are pre-tuned to center channel (does that mean channel 11 ?) I can retest on channel 11 and there is some adjustment built into the antenna to shorten the length into the base, maybe this may improve the SWR, but what could possibly be causing the difference in SWR between Low/High power and the overall low output power... Thank you for any help.
