Do a Google search for yourself, it's the first result that comes up. The DB-228 is the same way, it about 44 feet long overall. Paul

Very important. "DB" is a useless number without that third letter when rating antennas. (GRIN) I'd say generally that what you're describing is not physically possible. (Unless the thing is enormous.) The Sinclair SD-218 is 40' long, and rated at 11.5 dBd and has 8 folded-dipole bays. The antenna is taller than my 2 story house. <HYPERLINK "http://www.sinclairtechnologies.com/catalog/product.aspx?id=1693"http://www .sinclair-technologies.-com/catalog/-product.aspx?-id=1693> (They also work great. Two of them stacked on an 85' tower with a whole whopping 5' of vertical separation -- ha -- makes for one hell of a combined TX / shared RX system for multiple VHF machines at one of our sites.) So... there's no way a Super Stationmaster even comes close. The physics just don't work out. The much more commonly-seen SD-214 is 20' long and is 8.5 dBd. <HYPERLINK "http://www.sinclairtechnologies.com/catalog/product.aspx?id=42"http://www.s inclair-technologies.-com/catalog/-product.aspx?-id=42> Note: You lose 1 dB (dBd) if you get the Heavy-Duty/Low--PIM option. <HYPERLINK "http://www.sinclairtechnologies.com/catalog/product.aspx?id=2055"http://www .sinclair-technologies.-com/catalog/-product.aspx?-id=2055> Nate WY0X No virus found in this incoming message.
