Unfortunately, not any more. When I set it up, the antenna gave me an almost flat SWR on 27.330. It went up to 2.64 on channel 1 and 1.34 on channel 40. Resonance was at 27.435. Keep in mind that those figures came after several hours of tweaking. I was not going to mess with it any...
Does anyone have any experience with these? I have two of them.
The top section of my A99 got knocked around pretty well and stripped the threads. Compliance with property and zoning regulations here pretty much require that a stick antenna be used. I had a Radio Shack Archer crossbow 1/2...
The GMRS group in the Miami area has a repeater antenna up on top of a tall building, so it is several hundred feet up in the air. Boaters with GMRS walkie talkies have hit the Miami repeater from the Bahamas. The South Florida set up serves its area really well.
GMRS seems to have pockets across the country where it is popular. There is a fair amount of GMRS traffic in the Miami/Ft. Lauderdale area. There is also a small group down in Key West.
Similarly, most of us realize that an A99 really doesn't have 9.9 db (or even dbi) gain. That said, the Comet 712-EFC has outperformed every other GMRS omni antenna I've tried in real world conditions.
Question: Is it a half wave dipole? A half wave suggests you've got a half wave radiator. That would generate a lot of resistance and require a matching network. I think what we see here is a nice, neat center fed dipole.
Input and comments welcome
After much research, I went with a Comet 712-EFC. I've compared it to a few different antennas - including a 3db gain Sinclair, a 7.2 db gain Retevis MA 09 and a few others. The Comet delivers a lot of bang for very reasonable bucks. Our local amateur radio club was impressed enough that it...
End of Year SSB Net: December 28th (LSB 16) and 29th (USB 35)
The USB 35 experiment appears to have gone well. At the same time, some folks are still liking the LSB 16 effort - especially for the folks that still use old 23 channel radios. Let's close out the year with 2024's final week-end...
Given the various comments folks have shared, I've proposed to folks that we consider taking our SSB efforts to LSB 16 and USB 35. So, let's try a USB 35 net on Sunday, December 15, 2024 starting at 12:00 noon eastern time. We'll run all afternoon and make the usual effort to reach out every...
I've tried a few times over the last 10 days or so. There has definitely been some activity on LSB 38, but I haven't heard anything on LSB 16. But that's O.K. We'll see how our post-Thanksgiving LSB 16 net goes next month. I'm looking forward to it.
