Disaster? It's certainly stressful when a key "team member" goes down. One of our 40 GHz R&S VNA's woke up sick in the morning. It took 2 days of time and an eBay VME bus extender card to find the fault in a VCO (a cracked capacitor). Fixed (again)

A tree antenna? Does it work? You never need to guess an antenna's performance, that's why we test. See measured results for yourself at https://antennatestlab.com/biz-cards/pcb0048-tree-antenna … CONTEST WINNERS

Win a FREE Tree Antenna. Be a new follower or retweet any of our tweets before Monday morning, and you can win 1 of 3 Tree Antennas. Picked at random! Yes, it's a real antenna with an SMA connector.

Seasons greetings! In the front office we have an LPDA Christmas tree, some whiskey and some whisky. Does anyone else still have a "hospitality tray" for their customers anymore? It may be old fashioned, but it's here to stay.

We've just posted test results and 4-Dimensional gain plots of the
@rfspace LPDA-600-X-POL antenna. It performs well from 650 MHz to 3 GHz and doubles as a Christmas tree. Shown with a bottle of scotch for accurate scaling. https://antennatestlab.com/antenna-examples/example-3-vivaldi-antennas-rfspace …pic.twitter.com/ETkOXyXyyb

Here is a 915 MHz bazooka balun (sleeve balun) we created from copper water pipe. This is used for testing tiny 915 MHz PIFA antennas (for small coin cell sized radio sensors) so as to remove the influence of a large attached test coax.pic.twitter.com/bIVJxti8B9

An eagle flies in the chamber! Actually, we were just testing an eagle themed antenna. Notice where the center of rotation is ... it's at the base of the eagle's tail feathers, the presumed phase center.

Here is a great animation showing a RHCP/LHCP polar pattern of a spiral antenna progressing with frequency over a large 300 to 6000 MHz swept vector gain test. Evaluated in our far field chamber.https://twitter.com/HexAndFlex/status/1061379316305588224 …

We posted another interesting antenna test example. This is a large circularly polarized PCB spiral antenna by the talented @ihagster , and he will be offering them for sale.

Happy Halloween everyone. Pumpkins and an antenna? Why not? Black and orange are signs of Fall and now the cooler weather is in the air. Everybody loves a great antenna this time of year. The LPDA antenna is courtesy of

3D printing microwave antennas has gone well, and chamber testing proves they perform to spec. Here is a new "smoothing" technique using epoxy. This may be more "environmentally friendly" than solvent smoothing. More results soon https://antennatestlab.com/3dprinting pic.twitter.com/G64M5Ea9oK

Aren't these capped on the wrong end
While we appreciate the low cost of this 1000 piece batch of eBay SMAs, it does seem misguided to provide protective caps on the solder pins! What do you think? #antennas#RFpic.twitter.com/9JKalSKw85

This would actually do pretty well above 2 GHz. We've seen worse
