For that matter why don't we just use an antenna instead of a dummy load for tuning radios?
Seems like it would be close enough for government work

So instead of going out and purchasing a 50 ohm dummy load I suppose we could build our own 45 ohm dummy load for our test bench and accomplish the same results tuning a radio?
That impedance bump looks kind of nasty on a time domain reflectometer..This makes it obvious that you have no idea what the difference is between an impedance bump and a terminating impedance.

Physics is my hobby
then learn some history too.
a UHF connector (as designed) is not even suitable at todays UHF freqs.
Some of us that has been around "a while", always use the term UHF connector, and never say PL-259.
It's hard for anyone to take you seriously chop. You've got a reputation for starting these kinds of threads just to troll. In the past you've posted videos of what you want to hear and now you're using Google images. If you already know the answer you want to hear then don't ask.
If you want to believe only what makes you feel good that's fine. You are the type that asks a question just so you can reply. If you really want to learn about this stuff buy some books or take a trip to the library when you have some down time. If you want to learn about marks equipment and if he's using it right download the manuals, look over some radio service manuals. When you run across something you don't understand research it.
Everything you seem to know about radio has came from the CB techs you've used over the years. You overlook the basics and get in over your head. You say you're always looking for a tech that can do a better job for you and that's what makes people like you an easy target. You don't have enough knowledge to know when you're being taken by a smooth talking saleman. To keep it pg13 let's call it self inflicted sexual abuse.
If the radios are tube type (high output impedance) and have the pi-network to get the output impedance at the antenna connector down to something like 50-75 ohms, have at it.lol bump bump
maybe we all should direct connect coax to the pi filters of our radios 10-4
Copied directly from the link you posted RabbiPorckChop, if it's not worth worrying about then why start this thread? Are you implying that my antenna setup is seriously flawed and should be reconfigured without the use of UHF connectors?Conclusions
The strengths of a quality made UHF connector are the large center pin which can handle significant power and the relative inexpensive cost. The down side of an incorrect impedance are either not worth worrying about or are easy to compensate for at frequencies less than 500MHz.
