Horizontal only polarization has other weaknesses separate from the receiving antenna orientation, especially when it’s fairly close to the ground. Having said that, in hilly terrain it is often preferred.
This study in support of H only used cars with vertical whips, though.

There are many variables but the most important one is where is the target area and what is the terrain between the antenna and the target (and the distance).
Remember, natural topography causes reflections and when you send out the signal polarized only H or only V, it can get twisted. End of story, almost, but modern in window antennae, like Alfredo pointed out, are J shaped and are circularly polarized so they can receive most anything in any orientation. Transmitting circular pol helps to reduce flutter because even if it gets twisted, there’s still components in both planes. Also, H or V only transmitting results in more multipath issues.
The 60dbu of the new signal should clear both Hood River and Goldendale whereas the current one does not.
Seems like a perfect path to turning on a little on channel booster in each town. Once you have a 60 dBu contour, you’ve got a clear shot at a booster.
Cool… Jive Radio has posted photos of the KJYV antenna work.

(The site also has a note about some recent KJIV Madras coverage issues )
Filed 6/10/2020 (FCCDATA.ORG) KJDY LLC has signed a purchase agreement to acquire Burns outlets KSQB (FM), KYQT-AM and K256DC for $60,000. The seller is Alexandra Communications, a Northwest ownwership group.
(These Burns stations were on the market last priced at $80K. KJDY LLC also has a lot of cross-ownership interested, see My Eastern Oregon , myEO.)
Bend is getting a booster… the FM on-channel type. KJIV 96.5 obtained a construction permit for a one-watt booster near the edge of their 60dBu contour. It will be on a building with a pole (BPOLE) totaling 14.1 meters. The beam will be towards the northeast at 40 degrees.
KJIV broadcasts from the top of Grizzly Mountain near Prineville at 1kw ERP. They have an amazing music selection, available also at jiveradio.org .
Fields Pond Group has entered into an agreement to sell KICE to the Dove Media Center of Medford. KICE is licensed to Terrebonne but targets Bend from Powell Butte. It runs 2400 watts ERP at 94.9 Mhz at 582M HAAT, the C2 class max. The transfer price is listed as $315,000 per FCCDATA.ORG files. KICE has been running Fox Sports (previously ESPN Radio).
Dove Media owns a number of radio stations and is involved in cable and LPTV. (Nice market addition – the Bend area already has seven religious-programmed signals – KICE will make that eight.)
One trade press article said KICE “blankets the area.” If you look at the simple FCC 60dbU contour one would agree at first. Run the technical parameters through a Longley-Rice terrain-based propagation model and you will observe KICE’s many dead-signal zones. Like Medford, Bend’s terrain requires a translator or booster to make things work best.
KICE FM used to be KCOE.. “Central Oregon ESPN”, originally relaying the former AN 940 KGRL in some sort of LMA arrangement.. We all know what happened to AM 940 – still waiting for KWBY Woodburn to fire up those 10 kilowatts.

BTW, one of my first over-the-Cascades DX catches was the old KICE on 100.7. Troposcatter coupled with knife-edge defraction I suppose. Troposcatter, while common east of the Rockies is fairly rare in the Northwest…
As of 9 October the FCC has approved the sale of KICE 94.9 FM in Terrebonne to Dove Media. Fox Sports Radio in Central Oregon will soon be history!
Years ago when I had my Pioneer TX9100 with a Windgard 6065 FM Yagi, I used to hear several Central & Eastern Oregon stations including KICE. KWHT 103.5 I still hear from time to time from here on the coast.
