I agree with Chuck - you will have a difficult time receiving the local channels from Lincoln with an indoor antenna.

I live in Lincoln. When I moved here 5 years ago I started out using rabbit ears, but reception was very spotty and some channels I could never get.
I ended up buying a ChannelMaster CM2016 antenna -

My TV reception has been rock solid ever since. On rare occasions (weather, temperature inversions, etc), I can receive channels from San Francisco!

I hope this helps.

KTXL 1.5 Degree Beam Tilt Protest

KTXL, Fox 40, has applied to install a new broadcast antenna with a beam tilt of 1.5 degrees for the FCC repack switch from channel 40 to channel 33. The current channel 40 antenna has a beam tilt of 0.5 degrees. The change to a 1.5 degree beam downward tilt would severely impact KTXL reception in the Sierra foothills due to the foothill elevations being higher than the path and width of the broadcast beam. The area of service contour map provided by KTXL does NOT realistically consider the impact of a 1.5 degree beam tilt, and the reception shown for the Sierra foothill region is HIGHLY optimistic.

UHF broadcast antennas typically have a beam tilt of NO MORE than 1.0 degree, often 0.75 degrees. It is common for VHF broadcast antennas to have a 1.5 degree beam tilt because the beam width of a VHF antenna is usually quite wide compared to UHF antennas. A 1.5 degree beam tilt for a UHF broadcast antenna is extreme.

I earlier emailed Gary Cox, KTXL Director of Engineering, and Bob Karlinsey, KTXL Director of Technology, expressing my concerns and alarm over the choice of a 1.5 degree beam tilt. Below is the text of those emails. Only Bob Karlinsey replied, but not to my second email. I urge all concerned Sierra foothill KTXL viewers to express in emails their own concerns over the loss of KTXL reception following the implementation of the switch to channel 33 due to the choice of a 1.5 beam tilt and demand that a 0.5 beam tilt be retained as is current for channel 40. The FCC repack should NOT result in a loss of service to current viewers of any station. That is just NOT RIGHT!!!

Subject: New KTXL Ch 33 Antenna FCC Minor Modification Application

To KTXL Engineering:

Your FCC Minor Modification Application, granted on 6/16/2017 for a new KTXL channel 33 broadcast antenna, specifies a Dielectric TFU-22ETT/VP-R 3BP250SP with a 1.5 degree Electrical Beam Tilt. Your current channel 40 broadcast antenna is a Dielectric TFU-24ETT/VP-R 3BP250SP with a 0.5 degree Electrical Beam Tilt. I am extremely alarmed and concerned that the new antenna is specified as having a 1.5 degree beam tilt and hope that this is just a specification error.

I am a KTXL viewer in the Pollock Pines area. For the elevation beam width pattern of the new antenna, a 1.5 degree beam tilt would only permit a very small and completely unreliable fraction of the KTXL signal to reach the 3400 ft Sierra foothill elevation where I am located. The bulk of the signal would simply fall upon the slopes of the lower intervening foothills. I already have issues with the KCRA/KQCA/KMAX broadcast antenna which has the highest gain and narrowest elevation beam width in all of California. It has a beam tilt of only 0.75 degrees, and, of all the major Walnut Grove stations, KCRA, KQCA, and KMAX are the only non-viewable stations at my location due to the overly narrow beam. I have the best receiving antennas and systems available including an 8-foot parabolic dish antenna I recently custom built and designed at my own significant cost and labor, all to no avail. KTXL has been one of the strongest and most reliable stations received here, and I would hate to lose that station as a result of an inappropriate broadcast antenna choice.

Please tell me that the 1.5 degree beam tilt specification is an error!!!!! The 0.5 degree beam tilt you have now for channel 40 is just fine. Why would you increase the beam tilt and kill so much Sierra foothill reception???????

Hello ___,

The information you sent along in the email is correct for the channel change and installation of the new antenna system (FCC Repack).

The documented beam tilt is 1.5 degrees as you have researched and in the documentation provided to us by the manufacturer.

That being said, we are sorry that your reception of our signal may be in jeopardy due to the design and specifications of the new antenna.

We appreciate that you enjoy our programming and are hopeful that you will still have reception and will continue to enjoy our programming after the FCC Repack.

Thank you for contacting us and being a loyal viewer.

Sincerely,
Bob

Subject: RE: New KTXL Ch 33 Antenna FCC Minor Modification Application

As I understand, a customer ordering a Dielectric broadcast antenna specifies the beam tilt, and Dielectric builds and provides the antenna to the customer's specification. There is NO reason why KTXL cannot request the new antenna be built with a 0.5 degree beam tilt. YOU have the option NOW, before it is too late, to order an antenna built with the specifications appropriate to properly serve KTXL viewers within your service area, which includes the Sierra foothills. You are NOT locked in to a 1.5 degree beam tilt, which is unnecessarily excessive, and the repack should NOT be cutting off current viewers from OTA viewing! Please reconsider your beam tilt specification BEFORE committing to an antenna order from Dielectric. I refuse to be forced to pay for satellite or streaming TV services, I don't have high speed internet, and I have already shelled out enough dollars for antennas and HDTVs and HDTV PC boards. Please order a broadcast antenna which adequately serves your current viewers. The FCC reimburses KTXL for the antenna cost, and that money should be used to cover and serve all current viewers!!!

Ray,

This is exactly what I was looking for. I am bookmarking your response and once we move in, about two blocks from Ferrari Ranch Rd., I will use it to implement this solution. I believe the home we bought has an attic that will work. No matter what the law says I am not about to try an external antenna and invite the attention of my neighbors and the HOA.

You do what you want but just to be fully informed here's the link to the FCC rules regarding installation of TV and other consumer antennas:

Chuck,

I understand fully what you are pointing out. However, as we drove through the neighborhoods looking for a home to buy I do not recall seeing one house with an external Yagi type antenna. There were some Directv antennas but none of the larger Yagi's. I don't think I have the guts to withstand the bad vibes that will emanate from my neighbors. I hope the attic has enough room in it for one. I will be crawling around up there pulling wires for my home theater speakers so I will find out.
