I have a 40W Midland MXT-400. A 1 foot jumper of TM LMR-400 connects the output to an MFJ-842 SWR/POWER meter rated 140MHz-500MHz. A 3 foot RG-8X jumper connected to my window feed through (MFJ-4601N, N connectors). On the outside I have a lightning protector (also N connectors). The feed line is 30 feet of TM LM-400 connecting a BRC HP500 antenna.
The SWR meter indicates 35W output from the radio with approximately 2W reflected power and the needles cross at 1.4SWR.
A call to an individual I hear booming in from a repeater loud and clear with only two bars on my signal meter tells me that my signal is staticky and broken. So it appears that the receive is a LOT better than my transmission.
I suspect that I have an antenna marketed as a GMRS antenna that is in fact a UHF antenna trimmed for SWR, but not necessarily a GMRS resonant antenna. The ad says it is 3 5/8-wave on 2m and 7 5/8-wave on 70cm, and the frequency is 460-470MHz (GMRS) and "C-loaded" (ceramic capacitor at the bottom, probably?).

Any thoughts on this?
Thank you,
