Omnidirectional or conventional antenna
http://www.tvfool.com/?option=com_wr...f1f0be5fe414ea
Above is the link from the Analysis from our home address. We currently have a 15 foot antenna tower with a conventional antenna and rotor. We currently can receive channels from Milwaukee, WI, Madison, WI, and Green Bay, WI. The antenna comes loose from the tower sometimes and we have to climb up the tower to connect it again. It is not always where it should be. We also have windmills in the area and have heard that it interferes with the reception at times. We do not know if that is fact or fiction.
Our question is this: would an omnidirectional antenna work here as well as a conventional antenna? If so that would be extremely convenient to what we have now.
Thank you,
Patti

Reason: added cities we now recieve with current antenna

It's unclear what comes loose so I can't tell if there is a simple fix like tightening or replacing a few fasteners. Or is the existing equipment simply worn out and in need of replacement all together.
If I was in the same situation shown in your reception report, and stating from scratch, I'd focus my attention on the Milwaukee signals, at least to start with. Rather than using an omnidirectional antenna which lacks the gain and directivity that's needed in these weak signal conditions, I'd opt for a Winegard HD7698P which I'd point at Madison (134° per a compass). I would skip a rotator, once the aim has been fine tuned and the mounting clamp properly tightened, further adjustment should not be needed.
If you have more than one TV and /or a cable run of 50 feet or longer, I'd also install an Antennas Direct 'Juice' preamplifier. Many other preamplifiers are quite likely to have trouble with the powerful signal from WWRS (real CH-43).
If you want to go after the Madison signals, I'd test the viability of those signals by temporarily pointing the HD7698P toward 243° to see if those signals are worth the effort of adding a second antenna dedicated to that market.

We are sure we just need to tighten the bolts, it has been up for about 7 years now. As far as our reception, Madison comes in the best. Milwaukee is hit and miss, not sure if it is the windmills interrupting that reception or something else.
We will take your suggestions with the Winegard HD7698P antenna and see about the Antennas Direct 'Juice' Preamplifier. You talked about a second antenna, would we mount that on the same tower and how far apart from each other? They would both be stationary with no rotator I am guessing. That would be great although I am not sure how to connect them with one coax cable with out a connecter to go haywire.
Thank you,
Patt

It is the Iron Ridge Windmills that are causing our problems. We are about 4 miles as the crow flies. I guess there isn't anything we can do about it. Thanks again for the links. I appreciate it.

Maybe there is.
Your stronger TV signals are coming from Madison and Milwaukee, but your antenna would be facing in the general direction of the wind farm. The signals from Green Bay are weaker, but the rear of the antenna would be facing the wind farm which might reduce the interference from the turbine blades.
To have any chance, you would need a high gain antenna like the Winegard HD7698P, a good preamp like the Antennas Direct Juice or Channel Master 7777, and a single channel custom (expensive) bandstop filter for channel 43 from Tin Lee to reduce the overpowering signal from WWRS-TV. You would need to talk with one of their engineers on the phone and email him a copy of your tvfool report.
http://www.tinlee.com/MATV-Bandstops.php?active=3
The filter would go between the antenna and the input of the preamp.
If you would settle for just the UHF real channels (14-51), consider the Antennas Direct 91XG antenna instead.
You should try all three directions, because a high-gain antenna has a narrow beamwidth that might be better able to reject the interference from the wind farm, as long as it isn't aimed directly at it.
Raising the antenna height might help:
25 ft

50 ft:

No guarantees, but that is your best chance IMHO.

I thought this was interesting:

Can wind turbines interfere with television and radio reception?
Wind turbines can interfere with television and radio signals received through an antenna. However, given the distances between wind turbines and homes or businesses, the turbines do not interfere with satellite technologies because the signal is received from above rather than from a land-based broadcasting tower.
In the event that signal interference from wind turbines is experienced, We Energies is committed to resolving the issue and covering the costs. We have employed a variety of technologies and techniques in the past to mitigate the issue. For example, at our Blue Sky Green Field Energy Center we have established a program to restore the local channels for those experiencing problems as a result of the turbines. The program includes an evaluation of the resident’s situation and applying the right solution. In some instances, the solution includes servicing an antenna, installing a different antenna or replacing components of the antenna system. If the antenna adjustments do not resolve the matter, the hardware and local programming for satellite service is provided.
There have also been instances where residents have experienced interference with FM radio reception. After evaluation, we have found that a commercially available HD radio is capable of clearing FM reception, and we will work with impacted landowners to provide this equipment.
Regardless of the technologies used to restore television or radio interference caused by our wind turbines, We Energies is committed to providing a remedy for as long as the turbines are operating.
