Moxons work great, and they take up less space than full size two element Yagis
The Ashtabula County Amateur Radio Club is a group of amateur radio operators (Hams) in Ashtabula County, Ohio. We dedicate ourselves to all aspects of amateur radio communications, from emergency communications, to social gatherings, to contesting. Our club is open to anyone wanting to learn and participate, regardless of licensing.
The Vertical Moxon had everything I was looking for, a low TOA (Takoff Angle), wide horizon coverage, and good impedance loading. All of this was in a small enough package to fit in my relatively small back yard.

The great thing about Software is that you can improve it continuously. Here at NW Digital Radio, we view Hardware the same way. Each time we build out a PCB Fabrication run, it’s only engineering time and new solder-paste stencil charge to make any improvements. So we re-evaluate each product, looking for ways to make it better or appeal to a broader market.
Now that we’ve shipped hundreds of units, we’ve updated the UDRC based on feedback from the field.UDRC-II Changes:
- PTT and SQL are now independent and buffered on both ports making it a true 2 port controller
- LEDs have been added to both PTTs and the 5V converter (only lights if wired to 12V)
- The 12V to 5V converter has an RFI Filter and Transient Protection for Mobile Applications
- The Audio Inputs and Outputs are now 100 ohms to improve cable matching
- The EEPROM version allows the driver to auto-configure for the UDRC or UDRC-II
The UDRC-II starts shipping once we have all the documentation updated. All existing backorders will ship UDRC-II. The original UDRC will be obsoleted.Limited Time Offer for all UDRC Owners!
If you’ve already purchased a UDRC, place an order for a UDRC-II by the end of September and receive a $20 Rebate. Just write UDRC Rebate in the comment field. Your email address must be in our Customer Database to qualify.
