Wattage Ratings of RF Connectors

 

开云体育

Without having to get too deep into searching Google and other sources, is there a “one-stop shopping” reference where I can see the wattage ratings through various connectors?? I’m specifically interested in Type N vs. UHF connectors.? To start off, can a Type-N handle 1kW power transmission at VHF and HF?

Yes, an N will easily handle a KW at VHF and below. Truth be told, a PL259 will likewise handle it (it might warm but it will handle it)

I run 1100 watts on my 2 meter EME station and have a PL259 at the amp output. After literally hours of TX time, it's warm but not hot

But how warm does the green cheese get?

Mark,

It will likely depend on the individual connector, so therefore a single source listing may not exist, unless the connector meets a spec....like a Mil_spec. The best way to be sure is to consult the manufacturer's specifications and, of course, buy quality connectors. I have never understood the concept of of sinking thousands of $$ into antennas, transceivers, amplifiers and peripherals and then buying the cheapest feedlne and connectors to be found.

I will add? yes most will handle our ham radio legal limit ?will get warmer on digital? AM and FM … My observation that if? the SWR Gets high and? you are not aware of it I had a Connector ?get so hot it melted the solder .

Thanks, Ken; that was my concern.

?

When I installed my HF station, I didn’t have a linear. ?Now, I own a desktop kilowatt, and I wanted to ensure the connectors I used could handle the power before I started running the linear at full output.? (The primary feedline to the antenna is ?” Heliax with “N” connectors, therefore the inquiry.?

?

It is buried in the ground, feeding a Butternut HF-6V.? It’s worked GREAT so far (worked 3Y0X on 20 Phone with 100 W) and I’m anxious to see its performance once I add the power.) ?I had been told that the N “might melt the center pin” at power levels at or over 1kW, so I had to ask…

Sometimes it is not about the power as such but the voltage.

Good N and pl259? connectors are rated about 5000 volts peak or 1500 volts RMS.

If you are running an amplifier and have a high SWR the connector may arc over.? Coax will tend to do the same.

So you know, an N is almost electrically the same as BNC, but much more substantial mechanically.

You might play with various combinations of M and F N and BNCs to see a secret surprise.

Other than that, your question about power stand-off may depend a lot on how much power you're really pushing.

In the broadcast industry, a type N connector is usually limited to 600W or less at 100MHz. I have a 1200W Gates Air transmitter on the air currently on 1.44MHz with a type N connector as its output with out issue. PEP power is several times the carrier power. I have seen many type N connectors used at the KW level on 2-meters and above without any issue.

BTW...I am told that Motorola considers the type N connector to be "single use"...

Mark,

Using ohms law, with a 1:1 SWR, 1000 watts comes to about 4.5 amps and 240 volts.? An N connector should have no problem handling that.? Of course, as the SWR increases, depending on the location of the connector along the coax, it may have a lower current and higher voltage or vice versa.? Without an antenna tuner after the amplifier (assuming it is solid state and no built-in tuner), the power output will probably drop off enough on a mismatch that the connector will still be OK.? With an antenna tuner, there is the possibility that things could get interesting with a large enough load mismatch...

73,
WB9ACQ, Jim
