Initial results for handheld comm radio flight test
Hey Everyone. Finally got a chance to get the new external antenna installed. New RG 400 coax run that ends just to left of the left seat. Easy inflight reach to hook up handheld if needed. The yaesu FTA-550 has a peak 5.0 Watt transmission signal. (As a comparison, The Garmin SL 40 in the panel has 8 Watts. So the handheld has 37% less transmit power).
I've done a couple of flight tests with my Yaesu FTA-550 hooked to the external antenna and here are my thoughts. I was most interested in the range and quality of my transmissions using the underbelly mounted antenna. I didn't attempt any transmissions with the rubber duck antenna.
First test flight: I'm testing with my headset plugged into the handheld and using external mic setting so i can talk into my headset. Only thing is to remember to use the PTT on the handheld. At about 2500 feet, The longest range I got was 42 miles. The Mobile airport tower said my transmissions were about 4 out of 5. I wondered if Mobile tower had some kind of remote communication antenna. Pensacola tower was 28 miles and I never could raise them.
Second test flight: I was able to raise Pensacola tower this time. Distance was 22 miles with altitude of 2500. She said I was weak but readable. I spoke with another airborne aircraft which was about 20 miles away and he said I was loud and clear.
Random calls didn't get me lots of responses so I plan to do a few more tests with someone at my FBO stationed at the radio! Should yield more consistent and accurate conclusions. With the experience I have now, I feel the radio will work well as long as I'm under 20 miles with sufficient altitude. I don't think it will help much in the middle of nowhere using flight following. Within 15 miles of a terminal area I'm feeling it will perform well. Overall I'm feeling like the external antenna was a good move. More test to follow.
