DXE-AFHD-4 Antenna for home rooftop Hybrid Digital HD radio

I am awaiting shipment of a DXE-AFHD-4 antenna from the exclusive distrubutor, DX Engineering in Ohio USA. I will initially use it with two tuners: Sangean HDT-20 and Sony XDR-F1HD. Rooftop installation on a short mast on a two-story house on a hilltop is scheduled for May 29, 2020. Would any forum users be casually interested in hearing about my subjective impressions of this experiment? I will be comparing the new settup with the prior attic antenna setup. Also will be comparing it with a Grace Digital internet radio tuner and Roku Ultra SiriusXM stream and Tidal HiFi stream. I use the radio to listen to sports and discover music. Station KSER independent public radio in Everett, WA (state) has a 64kb stream. I prefer the radio broadcast.

By the way, Solid Signal also retails the DXE-AFHD-4 antenna. It is manufactured similar to discontinued InLogis and Pixel Technologies units.

Sure, I get alerts from this forum and like reading about antennas. This one looks like a 4 ft fiberglass whip like truckers use, such as the AM/FM FireStik.

I had a vertical steel whip hooked up for a while, a Metz SS-8 which was also sold at twice the price as a Magnum Dynalab ST-2. Those antennas got plenty of hype in some AV magazines but I found the performance pretty similar to the wire dipole thrown in with most FM radios so I eventually took it down. Vertical whips don't have much, if any, gain but I think the reason they work well for some people is because they get mounted up high on a roof, unobstructed by interior walls. If it ends up working well for you then that's the only thing that really matters.

Presently May 24, 2020 p.m. Westher forecast is looking A.Ok. for a rooftop antenna install next Friday afternoon May 29. One of two shipments of equipment has already been delivered. This will be my first rooftop antenna! Have been thinking back to the late. 1960's when I DX'd with shortwave and AM radio's. I remember Heathkits. Have looked at radio-locator(dot)com for anticipated reception. 75 distant and a total of 115 including fringe AM and FM stations for Lynnwood, WA 98036 my location. Many also on internet easily grouped on my out of production Grace Digital internet tuner. Looking forward to the upgraded antenna experiment.

fmfool.com is another good site to check anticipated reception.

Initial results of my antenna experiment are underwhelming.

Yeah that was my experience with a vertical whip as well.

If you're trying to get specific fringe stations that are all in the same general direction you could put up a directional FM antenna which would do a better job. Maybe add an A/B selector switch so you can use the directional antenna for those stations and the vertical whip for the rest if they're stronger.

Otherwise your choices are to put a directional antenna on a rotor, or stream the stations.

It's not 1980 any more, people aren't putting up big antennas like the old days. It's not really worth the effort, the streams work pretty well in most cases.

In my failed experiment I gained two FM HD stations that are close by and low powered. However I lost five FM HD stations that are high powered but furthur away. Phooey!

Sorry it didn’t work out.

I have had a somewhat similar experience, albeit on a smaller scale. I had to add an antenna for the radio I use on my desk in order to receive several stations I like to listen to. However, doing that killed a couple others. It’s ironic because the ones that were killed are weak at that location. Anyway, I have to switch off (or disconnect) the larger antenna when I want to hear those stations.
