Here's the diagram of Circular polarized FM antenna for FM broadcast band 88-108 MHz. If you want to stack the antenna use jumper cable as you can see at the diagram.
See more about FM antenna stacking. Welcome to experiment
FM Antenna Diagram in detail
Here's a simple fm antenna plan you can find. This simple ground plane antenna works well in the FM Band 88-108 MHz. It's built of a small plastic disk (around 5cm in diameter, not critical) and stiff copper wire (preferably enamel coated) some 3mm thick. It's omnidirectional, therefore it works equally well in all directions. This makes it suitable for most applications.

This antenna project written by Guy, ON6MU. The reflector and driven are copper. 1/4 inch copper pipe used shorting bar for gamma. Held in place using stranded copper wired. Permantly soldered in place after final tuning adjustments. 14 gauge wire with shrink tubing installed at SO 239 or N connectror. "Coax seal" on tip of gamma rod to keep out moisture, printed grey.

This antenna below is a construction of an Yagi antenna calculated for the FM broadcasting band 88 - 108 MHz. The central frequency used for 100MHz. You can extrapolate easily below for others frequency grace to values of diagrams. This antenna is less difficult to construct than the one presented on the previous page.

We were about to write "dish", but since a dish by definition has a bowl shape, we settled for "antenna" instead. But, this is no ordinary satellite antenna, as you can see from the picture.

Since your neighbors may not enjoy the sight of your new satellite antenna, you can order your Sqish with a custom camouflage.

"Wireless enthusiasts have been repurposing satellite dishes for a couple years now. This summer the longest link ever was established over 125 miles using old 12 foot and 10 foot satellite dishes.

There are lots of equation that are used during the calculation of antenna communication link. One of the most frequently used equation would be the power equation. Say for an example you have an antenna that total resistance of 50 ohm and there is a current supply of 220A, then what will be the total power used by the antenna?In such case you can use the formula P=I*I*R which is =220*220*50=2420Kw.So the antenna is using power of 2420KW.

If the inner wire is made from rod it is good idea to drill axially a 3 mm hole on the end of it so the rod can be solder firmly to the inner tap of the N connector. The length of the rod becomes about L/4, but it is better first to leave it longer and cut it later after the parts are first pre-assembled.The copper conduit must be split with a metal saw as accurately as possible and deburred with a file. The end of the split conduit is then fastened to the centre of the pan. It is not possible to solder it directly to aluminium but we made a flange from tinned steel sheet to same dimensions as the flange of the N connector. In the middle of the flange is drilled a hole equal the outer dia of the conduit and four 3.5 mm holes as in the N connector. The one end of the split conduit is then s
