No more info on when they'll be available I guess?
My best guess is production will commence sometime between Thanksgiving and Valentines Day. The engineer is still finalizing the DB4 phasing lines, then the plastics engineer needs to design the molds for the plastic pieces, the molds have to be built, the plastic pieces have to be produced, then the antenna assembly can be done. It's a long tail that wags the dog on a new product!
Give Mini-Circuits a call re Surface Mount Device (SMD) Balun Transformers, but it looks
like the loss at 700 MHz might be closer to 1.5+ dB:
PS: 200:50-ohm is IDENTICAL to 300:75-ohm transformer.....both are 4:1 impedance RATIO....
We have already investigated this idea and rejected it. While the impedance transformation ratio is correct, we don't know know what kind of mismatch losses would be incurred using a device specified by the manufacturer for different impedances than our design intention. It would probably work okay for some of our antennas at certain frequencies, but our engineer indicated he wasn't interested in the 50:200 baluns. He's the one with all the degrees and design experience, so I'll defer to his judgment.
I called them last winter. Vaporware. Product was never produced. I have found an interesting candidate from Murata (DXP18BN7514T) that we may look into.
It's great that this antenna is being made specifically for the spectrum 7-51 with the best gains from 14-51.
See post #15, please. I haven't seen any simulation data on high-VHF yet, so I'm suggesting that UHF performance be the subject of conversation. Please also remember that our ClearStream UHF antennas were specifically designed for 14-51 and have been on the market for two years. So far, they're the only commercially available antennas designed for the new UHF band.
As far as other new stuff that's already in stock, we already have a cute little variable line amp available along with our new coaxial 5-in-1 tool (perfect for the homeowner or the weekend warrior). This week, we should be adding a 15' telescoping mount to the website ...but I digress from the subject of this thread.
Regards to all!
