Review of the Cushcraft R-9 multiband vertical. By KC1ACF mark Vess
After searching for several months for a multiband vertical, I began to look at the Cushcraft R-9. I found a number of reviews on it but they were either disappointing or incomplete with only a few extoling the virtues of this antenna. I wanted to have a vertical multiband with no ground radials for our club Field Day up high in the air and not on the ground. This is the tallest of all 80M thru 10M verticals. This is the antenna for the job! The R-9 assembled easily over several days with some patients and scrutinizing of the manual. The antenna was installed on an 18 foot long car trailer with a winch, a base hinge and an aluminum 20 foot tower. Six feet of 2” multi-wall mast connects the antenna to the tower. Two sets of guy lines on the tower and above the vertical traps keep things aligned during wind gusts. This is a must have!
The Cushcraft R-9 was a match on all bands right out of the box by following the assembly instructions carefully! I used Vernier calipers in two sizes to set it up. I made no adjustments to this antenna. All bands, 80, 40, 20, and ten were close to 1 to 1.1 and less than two. The analyzer arrives tomorrow to finalize tuning but so far I have enjoyed all good contacts from eastern USA, Canada, Saint Croy and Italy. I have used a 270’ Buckmaster 9 band OCF dipole for years and an ongoing A/B comparison shows the R-9 equaling or surpassing the Buckmaster on 40M and 20M. The R-9 excels on 10M and is a couple of Db’s below the Buckmaster on 75/80M. I have yet to try 6M, 12M, 15M, 17M, and 30M. This is a great antenna overall and it truly works on all the main bands so far. Stay tuned for the results on the other bands. Mark, KC1ACF
