Your points are well stated, realistic, and understood. Thank you for taking the time to explain your viewpoint.
I still don't know what to tell someone with strong local FM transmitters other than you are SOL, don't aim a VHF antenna that way, use a HLSJ (if there are any left), use a UVSJ to limit your reception to UHF, forget about DX from other DMAs, etc. |

Thank you for your test results; I will need that information to help others. I'm wondering how it would do with this FM report with FM signals about 30 dB stronger than yours: http://forum.tvfool.com/attachment.p...9&d=1457391314 http://forum.tvfool.com/attachment.p...9&d=1457391314 |

A bit of an update, since my last post the CPA-19 started to sputter work again as it did before the total burn out (?) i.e. in the 220 magnetic sweet spot I'm able to put in 27 channels, oddly WHTV Jackson MI https://en.wikipedia.org/wiki/WHTV very clearly most times of the day which boggles my mind due to the antenna direction, station power/location, totally freakish when ch 7 is totally out of the picture.
So anyhow I decided this was enough to get me by so I passed on the Televes but now Solid Signal has the HDB91X http://www.solidsignal.com/pview.asp...source=inhouse on sale for 35$, being that its such a low cost & could use it conceivably at my future home I thought I'd grab it & put it on a tripod inside the room by the outside jmount since it won't fit on it due the the dimensions. I know it will get questionable results inside but it will eventually get an outdoor mount when I move. I might connect a A/B switch to toggle the present antenna since it pulls in the locals pretty well. |
Funny how the design and naming look so familiar on the solid signal antennas!

Well the preamp finally burned off for good it seems & I can hardly pull close range local channels from the roof, I get more from the indoor HDB91X, but in a brick building its not great, as much as I hate to buy another antenna, that I ultimately won't use when I move, I've been considering getting a HDB4X, that is currently on sale at Solid Signal $25, as a quick fix, to put on the northbound wall Jmount that I originally used before I moved the db4e to the roof. With the pole I bought for HDB91X I think I could hoist it above the roof gutter. I've been wondering how the HDB4X compares to the db4e since the design is very similar but it only quotes a 50 mile range to the db4e's 60+, I guess for $25 I can gamble, at worst I could stabilize the local channels for the short run, not even being able to do that is pretty annoying.

The HDB4X is definitely not equivalent to the db4e, so the 50 vs. 65+ miles range is pretty accurate & nothing beyond that, on the plus side I don't seem to have FM breakup issue with WTOL 11 that I had with the db4e before adding a line filter, but I'm not sure if anything has changed in the last 5 years that resolved this outside of the antenna. Regardless the local 21 are stabilized with this on the Jmount, I was hoping to reach the stronger Detroit channels but that's not going to happen with the HDB4X.
