Channel Master 4228HD for VHF? Arlington, VA.

I am setting up a OTA air antenna for my condo. Currently for a testbed we have a C2 on the roof, and get most all of the Baltimore and DC channels. With the exception of the VHF 11,13 Baltimore channels, and sometimes the local DC channel 9 is flaky.

I have seen some reviews of the channel master 8 bay, and while it is not a VHF antenna it seems to do have a small db gain with channels 9, 11, and 13. Would you recommend this antenna or something else?

Also we are looking at getting a blonder-tongue amp for the building. We will split the antenna with 50 units. Is this a good brand, or would you recommend something else?

You may just need an FM trap to fix channel 9, but the C-2 is not the best choice for your situation. I wouldn't recommend a bowtie style antenna in our area either as they are less effective at rejecting signal reflections.

The Winegard 7694 should provide an excellent signal on all the major DC / Baltimore stations except MY 24 out of Baltimore. You may even be able to bring in the MHZ channels out of Merrifield & Manassas reliably as well with a bit of fine tuning. I have a 7694 & RCA ANT-751 sitting in my shed you can test with if you like.

Not sure what to recommend for distribution as signals are pretty hot & may overload. I've tried the Channel Master distribution amp in North Arlington & was very surprised how well it handled strong signals, but your strengths on WFDC are searing.

With 50 units watching, don't try any shortcuts. Get a real VHF antenna.

Given the size of your project, here are some guidelines re. the design of an MATV system. Not the final word on the subject but helpful (IMO).

Serving this number of users justifies the use of commercial grade components. Blonder-Tongue, Pico Macom and other names come to mind. The Holland Agile Digital Signal Processor comes to mind... http://www.techtoolsupply.com/Produc...Code=HPH-860AD One per real RF channel would be used to shift the antenna derived signal to a different RF channel, with the output level stabilized and at a level that could drive the distribution network.

I agree with TG, you will want to get this right the first time. With 50 users, your phone will ring at 3:06 AM if there is a problem. You will be a small scale cable provider.
