Loaded Antenna

Using a choke, you can shorten the length of your antenna to less than 12 inches

Effectively you should have the same range as cutting your antenna in 1/2.

Warning !

Modifying you radio in anyway may cause it to malfunction causing the lost of your model.

These measurements were done with the TX antenna extended 9'' 2 meters above the ground and the receiver (feather) antenna 1.5 meters above the ground.

Make your own coil using 31 turns of #30 enameled wire (get it at Radio Shack), closely wound on a piece of 1/8" wooden dowel. This equals the 1.5 uH choke.
