    I had no idea that 90 degree connectors was a thing.


    Don't forget, we are all engaged in a battle to the death against mediocrity.

    The best radio mic system that money can buy is ALMOST as good as a $20 cable.

    Yep, RF doesn't like sharp bends. I was taught a
    long time ago when dealing with things around 7 to 20 MHz, don't bend the coax hard, nice easy bends are best.

    It might not be too much of a problem on the transmit side of things, you will get some loss at bend as it radiates out of the coax. If you have plenty of power then wasting a dB is fine. But that same loss will happen on the receive side of things, and this is where you want every thing that the antenna picked up to make it to the front end amp.

    You can get in trouble with just using too much coax on a receiver. You mount some nice high gain directional antenna, let's say it gives you 9 dB gain over an 1/4 wave whip attached right at the receiver. If the loss at frequency is higher than 9 you just screwed yourself.

    An example 100 feet of RG-58 at 450MHz is 10.6 dB and that assumes no nasty bends in the cables. Keep bend radius to more than 5 times the cable outer diameter and yiu should be fine.

    Nice, I didnīt know about RF and bends either.

    here is a nice calculator for finding cable rf - loss:

    If I remember my desktop video days correctly it's not just rf loss that's a problem with tight bends/cable kinks, they can also cause reflections in the line.
