Message: [QUOTE="EscapeVelocity, post: 21152, member: 3771"]Do It Yourself DIY AntennasQuick note about the DIY designs here.  The Rhombic is by far the best, offering high gain and high F/B Ratio directionality.  The Yagi and Loops next @ about 5 to 6 dBd gain, and then the Twinlead Folded Dipole and J-Poles at about 0 to 1 dBd gain.  The Rhombic is very large and a bit tricky to make, however.  The Loop offers the best ease of make to performance ratio, IMO, though the Yagi offers better Rear Rejection F/B Ratio.  The Half Arsed Zip Cord Antenna (properly sized) is a pretty good temporary antenna until you can upgrade to something better...it has impedence mismatch losses and standing & reflected waves which reduce its effectiveness, but still offers something in the range of -3 to -6 dBd gain.VHF/UHF/FM Combo AntennasYou can use your television antennas as an FM antenna as well.  A lot of VHF antennas or UHF/VHF combo antennas can be used as FM antennas.....as FM is smack dab in between VHF Lo and VHF Hi bands (closer to VHF Lo).  So there are literally thousands of VHF television antennas available for use as FM antennas.  Not every VHF antenna is for FM though, some have FM traps integrated into their circuitry to tone down FM interference in the VHF High and VHF Low Ch. 6 television frequencies.  Generally speaking, television antennas that cover VHF Low peform better on FM than VHF High only or VHF High/UHF antennas...though all of them will work for FM.  UHF only antennas, not so much.  Many of these TV antennas are already installed on peoples roofs.  If you have such an antenna, then all you need is an FM Band Seperator and youre in business.  See the Winegard CA 8800 FM Band Separator below.  Here are some examples...Philips MANT510<img src="http://i302.photobucket.com/albums/nn88/EscapeVelo/IMG_0101.jpg" class="bbImage" alt="" data-url="http://i302.photobucket.com/albums/nn88/EscapeVelo/IMG_0101.jpg" />Yes, even indoor UHF/VHF antennas will work.  Some of them incorporate FM Traps though.  This one does not, it also is amplified.  Make sure you adjust the Rabbit Ear VHF Dipoles to the appropriate length for best functioning....about 50" to 60" total or 25" to 30" a side.Channel Master CM 3016 <img src="http://pimages.solidsignal.com/CM3016_zoom.gif" class="bbImage" alt="" data-url="http://pimages.solidsignal.com/CM3016_zoom.gif" />This one is particularly good on FM....with its quad-V Vhf section.<a href="http://www.aphenos.net/misc/electronics/suppliers/Winegard/wnhd7082.jpg">Winegard 7082P  </a><img src="http://www.a1components.com/images/thumbs/WIN1336t.jpg" class="bbImage" alt="" data-url="http://www.a1components.com/images/thumbs/WIN1336t.jpg" />A fine example of the all band VHF Low/FM/VHF High/UHF antenna.Channel Master Crossfire 3671<img src="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/ChannelMaster3671.jpg" class="bbImage" alt="" data-url="http://i302.photobucket.com/albums/nn88/EscapeVelo/EscapeVelocity%20Blog/ChannelMaster3671.jpg" />Excellent FM Antenna!  Well built too..[/QUOTE]
