#50ohm
Me, eating a bowl of pasta, but upon closer inspection it's actually just a bunch of coax cables drenched in alfredo sauce with 50ohm terminators mixed in

Und jetzt eine Premiere! Der erste Bausatz für #amateurfunk bei uns im Shop :). Stolz zusammen mit 1DLFLO und dem DARC e.V. entwickelt.

Dazu gibt es auf der #HAMRadio übrigens einen Extra Workshop. Gerne #weitersagen 😍

Was sollte als nächstes in den Shop? :)

And then for some reason you'll find all your terminators are 50Ohm while the cable is 75...

Cutting another 50ohm strip for some filter experiments around 400MHz. On nanoVNA, It has a nice yellow dot scribble more or less on 50ohm instead of any unsatisfactory arc around it or one end launching out of it. Cheap two sided copper clad. #rf #ham #electronics

GM's tracking me and selling my driving data. Time to fight back.
For $5 I got a FAKRA-Z to SMA adapter and a SMA 50ohm terminator. Find the FAKRA-D OnStar antenna jack behind the center controls. Unlock. Install terminator. Bye bye 👁️nStar, easily reversible.

do NOT impedance mismatch a protogen's 75Ohm coaxial in. Using a 50ohm cable and connectors may seriously impact on vision and hearing systems!

anyone got any insights on this $8 thrift store mystery device?

I buildt a 5/8 on 15m for a sngle band contest effort a few years ago and it worked really well! Does need a match to get to 50ohm input imp - this is quite a practical write up of something very similar to mine www.pa3hcm.nl?p=902

Loving your set-up!! I'm sure I've got some spare flexiweave here somewhere, we could make a 20 or 40m inverted "V" for you to try? I'll speak to @g7kna.co.uk about how to feed it with 50ohm coax, as we use ladder line for ours. It's a very efficient antenna, and may make a big difference to you 👍😊

RG-58 on oikein oivaa antennikaapelia. Puretulla 50ohm 10Base2:lla taitaa olla suurin osa noista <400W antennista johdotettu ;)

My RG174 50ohm coax cable, SMA connectors, and NooElec adapter box arrived!
This weekend I'm hoping to build a double cross antenna to receive NOAA weather satellite imagery.
I'm deciding if I should use solid copper rods (grounding stake), copper tubing, or galvanized wire.
Also Bun Inspector!

A 50Ohm resistor able to dissipate the transmit power that the IC7300 will generate when trasmitting. It provides a matched load that allows a transmitter to be operated in the absence of an antenna

You can literally use a $10 roll of lamp cord split in two for an antenna. Receiving and transmitting are very different games; for transmitting you need the 50ohm coax and all that. Rscieving? A cost hanger.

Sovitus ei ollut lopulta hääppöinen, eli olisi vaatinut enemmän aikaa viilata se kuntoon. Pelkän 50ohm päätteen laittaminen laitteen liittimeen kiinni olisi taas ollut aivan liian hyvä ollakseen totta. Ajatus oli siis, että uusi kesätyöntekijä sai muka vartissa tuunattua designin kohdalleen 🤭2/2

Another load of stuff from Ebay arrived today, A mixed lot of RF connectors and adapters.
Lion particularly was after the GR874 connectors.
These were a wierd sexless 50ohm connector by General Radio and just about unobtainium now.
They are used on some items of test gear lion has in his 'stable'.

I was a university IT mgr; nicking the mouse balls was common. Also removing the T pieces from the BNC cables and plugging the cable straight into "their" PC "to make it faster"... 🤦‍♂️ A lot of IT support was replacing 50ohm terminators, mice and so on. Thank god for twisted pair cable and LED mice! 🤣
