Came across this stash the other day, was told: grab what you want before it goes .. 😳🤷🏼‍♂️🤯 
RF absorber panels like these are expensive and hard to get at as a private person, so I filled my little car 😂

I was bitten by an Alias this morning. Not sure if it's poisonous or not. Nasty and fast moving. #rfengineering #RFDesign

A LEGO kit for RF engineers. 🧩📡 Open-source RF building blocks for creating custom microwave systems faster. 👇 #RFEngineering #OpenHardware #SDR #RFDesign

Did you know that crystal oscillators are orientation dependent? Well they are 😎 Albeit in the milliHz range for a 10MHz OCXO, the frequency change is completely measurable when you rotate the unit and change the crystals reference to earths gravity 🙂🙂 #rfengineering #hamradio #testandmeasurement

Higher antenna gain can mean a stronger signal in the main beam and less room for aiming error. This horn antenna demo shows the trade-off. How wide does your coverage need to be? #RFEngineering

Walls and corners shape wireless coverage. What if engineers could create a surface to help guide a signal through a difficult space? Explore reconfigurable intelligent surfaces in Need to Know. #RFEngineering #RIS

High-frequency systems demand speed + flexibility 📡 VCOs (Voltage-Controlled Oscillators) enable: • Wide frequency tuning • Fast signal sweeping • Real-time RF control From 5G to radar, frequency agility drives performance ⚡ #VCO #RFEngineering #5G #RadarSystems

One of those “it’s you or the dumpster” moments… How could I possibly reject that? 🤷🏼‍♂️🤭 #rfengineering #rfengineer #hamradio
