![]() The performance is outstanding! The bandwidth for this antenna far exceeds any yagi I have purchased. The manual was nicely written and I had the antenna put together in no time. Everything fit exactly right and the material used is first rate. I was first impressed with their manufacturing process in the material. So, never having a Corner Reflector, I went ahead and purchased one from Arrow Antenna. ![]() I always had problems with these antennas functioning outside the ham bands while maintaining some sort of gain. Guess I should mention that I'm using this antenna to communicate with the AO-7 satellite and as you can tell, I would recommend it.įor quite a few years I have purchased several brands of vhf yagi to serve as a point to point MARS packet circuit with another station approximately 50 miles away (as the crow flies). I hit a repeater 180 miles out with that power. ![]() Flat SWR on 2 meters and 440, even when I upped the power to around 80 watts with an amp. ![]() It's built more solidly than ANY antenna that I have ever seen made for amateur radio. To get it home (after buying it at a HamFest for $100) I hooked it on the roof rack of my XTerra with three short bungee cords, and drove at 55MPH to my QTH, Doing so didn't phase the antenna at all. I'm able to hit repeaters on 10 watts that are over 100 miles out with the antenna 8 feet off the ground hanging from one of those L-Bracket TV satellite dish mounts. Point it to space and I work satellites! Pump up the power and the fun just keeps happening!Įarlier 5-star review posted by N0TES on I have always lived well outside the city limits and found that I can hit every repeater from 30 miles out with this antenna and 1 watt. This might be remedied by adding a 222 MHz corner reflector antenna at its reverse on the mast.įinally, and I realize this is antithetical for hams, but before assembly: read the instructions, inventory the parts, and examine the pictures on arrow's website. unless your situation seeks a unidirectional deployment, the CR 146/440 could be unwieldly with a rotator, especially given all its weight is in front of the mounting bracket. the deployed size of the structure and mount took about a third of the condo's small screened lanai and some mild complaints from the XYL the 7.5 pound weight made the antenna easy to turn with an up to minus 60 dbd rejection to the rear of the antenna, there was no extraneous noise and no rf safety issues inside the condo with the sliding glass doors closed the 10dbd gain gave me a significant outgoing and incoming signal boost. It appears that the corner reflector is doing most of the work. The mean elevation for Florida is 30 feet. On the same coverage area for 70cm, and running 100 watts, I could regularly activate repeaters at a distance of 45 miles with my longest full quieting contact being 70 miles. My longest full quieting repeater contact was 156 miles in a direct line from the antenna's center. In the 215 degree wide coverage area(s), I could regularly activate 2m repeaters in the 75 mile range running a maximum of 85 watts. I used a 35 pound cast iron patio umbrella stand and 1 1/2" diameter, thin walled, steel mast. The feedline consisted of 25 feet of LMR 400. The SWR, only measured in the repeater and simplex portions of the 70cm band, was consistently 1.3:1 to 1.4:1. When assembled the SWR varied from 1.1:1 to 1.3:1 across the 2m band. The center boom was about 30 inches and the total spread between the left and right reflector arms was almost six feet! However, with a 60 degree beam width, a hand turn gave coverage to about 215 degrees out of a possible 360 degree coverage area. The CR 146/440 was larger than anticipated when assembled. Any 2m/70cm repeaters to the south, southwest, and southeast were, and mostly still are, blocked by the building itself. But, my goal was to be able to activate repeaters to the north, west and east from my screened lanai. I could hit a few repeaters to the north and west with a 2m/440 vertical. I live in a condo about 30 miles outside Tampa. I recently purchased an Arrow CR 146/440 corner reflector.
