    At 3:40 you made a point about TX loss. Since 3db is equal to 1/2 an "S" unit, you also lost 1/4 an "S" unit of receive in that coax. 😮
    Good discussion, thanks Rooster.

    So I put a new end on my LMR 400 today and it's not the ultraflex it's the solid. It absolutely sucks to lose that much when you can't afford big wattage. It is what it is for me. Great info I'll keep in mind when I win the lottery lol!

    Get the BEST antenna you can, with the BEST coax you can, and get it as HIGH as you can, and that is the BEST component of your system. Worry less about watts, and focus on the antenna and feed line.

      I have been running A homemade Dipole 10 foot off the ground inverted V with 30 foot of RG8x and Anytone 5555 Nii. I make it to New York from the Coast of California no problem on SSB. I could only Imagine if I had a nice 4+ element beam and 500+ whiskeys on a tall tower. I have also made some nice contacts on 27.285 AM. with same setup.

      As long as you have 1/2 or 5/8 lamda antenna on 11 meters height is benefit up to about 1.5 wavelengths . Beyond that at 2WL a 1/4 wl marconi will outperform for low angle far field radiation for skip. Local ragchewing diff scenario. No 1 antenna works best for EVERY application

      @@eastcoastmecca7109 I have it set to talk DX. Most of the locals around me are noise makers or like to start fights on the air. I have not used my Vertical in a long time. I need to find a way to set up a beam but I am limited to what I can have in the air. I have to bring my vertical down when not in use. Its a pain in the butt.

    this calculator is great ! I found that the loss on RG-8U that we used in the 1940s - 1970s has less loss than RG-213. So if run less than 2kw its benefitual . I we are between 2kw and 5kw than we need to use RG-213.

    I'm sorry I'm just not a LMR fan I believe they're full of
