i have 2 Philips MANT510 amp antennas in my attic. one is on the east side and is hooked to my lcd in the bedroom and the other is on the west side and is hooked to my plasma. i switched out the lcd for a ln52a750 and it doesn't seem to bring the channels in as well as my old 4095 sammy. i have directv hd, but rely on an antenna to pick up the locals in hd since dtv doesn't offer them. i read about the closehanger diy antenna and thoght i might try one to see if it helped. my question finally is, could i build one of these (or buy one if someone has a suggestion for a better one very cheap), put it in the attic and hook the Philips MANT510 in with it using a splitter so that i would get the benfit of both antennas? if this concept works, could i hook all 3 antennas in series with a splitter at each antenna and feed the signal to both the tv in the living room and the bedroom. i tought this might help since the antennas would be in different locations in the attic, but i am unsure if the signal from the antennas are able to be wired in "series" this way. is there an antenna guru out there? thanks

Yes but it is more complex than that.

Just combining three random antennas won't do much (if any) good.

The poor signal and noise from the "bad" antenna" will combine with signal from good antenna and degrade it.


The only time it makes sense to combine antennas is when they have a specfic purpose.

For example:
A UHF antenna and a VHF antenna. The UHF antenna will have a filter to filter out everything but UHF signals. The VHF antenna will have a filter to filter out everything but VHF singnals. So when the antennas are combined the duplexed signal is the "best of both worlds".

A slightly more complex example would be a main antenna that picks up everything except one channel which is on a different bearing. An second ant is setup on the different bearing to pull in that single channel lets say channel 13 for example. A special duplex is used filters ch 13 from main antenna and filters everything EXCEPT 13 on the 2nd antenna. This way a strong and clear 13 is added to the feed.

Last example would be parallel antennas. Two antennas with similar characteristics are setup in parallel (facing same bearing). They are combined to boost signal.

However what you described would simple join a bunch on unaligned signals and likely end up with poorer signal.

Unless you know what you are doing, this solution will be more likely to increase multipath than to help.
