"An inverted vee antenna is a modified dipole antenna supported in the center with the ends lower than the center. Viewed from the side, it looks like the English letter "V" turned upside down, hence the name. Inverted vee antennas are commonly used by many amateur radio stations, and aboard sailing vessels requiring better HF performance than available with a short whip antenna." - Courtesy of Wikipedia.

Great Work !!! well explained.
ReplyDeleteWhy didnt you consider putting a 1:1 Current Balun into the PCB and potting the whole thing? Version 2 of this antenna perhaps.
ReplyDeleteHi Aravind,
DeleteThanks for the great idea. I guess we are going to go into testing mode now and once we try out the results will be posted.
Again thanks for the suggestion...We value your ideas and suggestions.
Team RnD
very well explained with photographs !!
ReplyDeletehowever, should have also included the details of making the RF choke balun.

Hello,
ReplyDeleteThere is a simpler way to stand pole on the roof. Get hold of a old paint tin, which will be about 9 to 12" in height. Place a bamboo pole in it. Fill it with gravel or sand. If the pole is say 15 feet at about 5 feet level tie three GI wires as a tripod for support with the nearest possible structure. Before this have a egg insulator on the top of the pole with a rope to hoist the dipole.
