73 Greyline Performance
Just now getting started with the project (due to Pittsburgh winters). So far, the quality of materials far exceeds expectations.
Can’t wait to get this thing up and running.
I was positively surprised with what strong and solid elements the mast was made of.
I really glad that I have my antenna now. It fits in perfectly with my house and available space for an antenna.
I have the antenna mounted in a 4 foot long 12 inch diameter sonotube, with about 8 inches of gravel in the bottom and the rest in concrete. We have had winds of 30 MP/H this month and the antenna has been fine.
Here is the good stuff: After discovering and correcting that I was feeding the bottom 4 feet, and not the top 24 feet, this antenna can really transmit. I have been received on FT-8 as far away as Antarctica and Zambia transmitting at 40 watts. I have SWR readings mostly below 1.1 across 80 meters to 10 meters, thanks to the LDG antenna tuner. On 160 meters my SWR stays below 2. On 6 meters, the SWR gets up to 3, which is still usable.
I am still having issues with reception. I think it is mostly due to noise, and I am not blaming the antenna for this. The antenna sits 3 feet from my house, 18 inches from the eve. My local ordinances require the antenna to be set back from the property line by the antennas height, so not a lot of options for location at my house.
I recently added MFJ-915 common mode chokes to both ends of my feed-line, in addition to the Palomar unit provided by Greyline. This has significantly reduced my noise, at the cost of slightly worse SWR readings. I have not had much time to test with this new configuration. So far, my most distant SSB QSO has been 2 miles. I have more than a dozen FT-8 QSO's across the USA.
My only outstanding issue with the antenna is the flag pulley which goes at the top of the antenna. The one I received is twice the diameter of the antenna, so it won't clamp down on the antenna. I am still waiting to here back from Greyline on this issue.
In summary, this is a really nice antenna. It takes some time to get one, but I am happy now. I hope to resolve my noise and sensitivity issues eventually, but based on my transmissions, I don't think it is an antenna problem.
