Simple to install & easy to use, plus it works as well as any of the other three mobile antennas I’ve previously used. No wonder it took a long time for me to find an Alpha MOTO that someone was actually willing to sell. Last fall I was at a hamfest, and after much searching I found a ham who was leaving HF mobile and I quickly bought it from him.

This mobile antenna has a transmatch at the base of the main element, which the manufacturer calls the Alpha Match. To install the antenna I just screwed the universal 24×3/8 thread (at the base of the Alpha Match) onto an Alpha Jam mount from the www.AmateurRadioStore.com. After I attached my coax, one touch of my automatic tuner, and I was enjoying QSO’s.

I recently parked right beside my base antenna, an Alpha DX-CC (different company) 80, 40, 20, 15 and 10 meter dipole at 35 feet in my trees, and installed an A/B switch so I could compare signal strengths. On both Receive and Transmit the Alpha MOTO was down 1 S-Unit on 10 Meters, equal performance on 15 meters, down 2 or 2.5 S-Units on 20 Meters, and down 3 or 3.5 S-Units on 40 Meters. Just for fun, I tried 80 meters, and received one report that was 4.5 S-Units difference.

Based on my experience with this antenna and a review in RadCom Magazine of the Alpha DX, I bought the Alpha DX Antenna. It wasn’t too hard to find the review, I simply went to www.rsgb.org and searched for Alpha Antenna in the “Search www.rsgb.org” box at the top right of their web site. I imagine the review is posted somewhere by or is available upon request from Alpha Antenna.
