David, Its a Hi-Z Triangular array, it is only a rx antenna, not for transmit. Used to be sold by Hi-Z themselves but now sold are now sold albeit at a higher price by DXEngineering. You can read about their antennas here: http://www.hizantennas.com There are links on their antenna pages to DXEngineering to purchase the one of your choice. I chose the triangular array because it offers 6 directions of forward & of course, 6 opposite directions of null.
They have other options which may suit you better depending on your spare pounds and QTH. Look on eham for reviews: http://www.eham.net/reviews/detail/11548 The following link also but it reviews several of their systems: http://www.eham.net/reviews/detail/8579 I am extremely happy with this triangular array with the K3; lower price and very effective. Hi-Z notes they are for low band use but I have found them a godsend on the upper bands as well for I have no beam and use wire antennas hung in not very tall trees. If you are looking for even better performance but only 4 directions, their 4 square gets very high ratings. Their 8 element gives the 4 square performance but with eight directions to chose from. And... their 8 element comes in two different varieties optimised for 80 or 160M. 73, > Gary > > I am very interested in your 'steerable' antenna for 160m, would you care to > advise what you are using? > > 73 > > David > G3UNA > > ----- Original Message ----- > From: "Gary Smith" <g...@ka1j.com> > To: <elecraft@mailman.qth.net> > Sent: Saturday, February 01, 2014 7:03 AM > Subject: Re: [Elecraft] K3 Rx antenna > > > > Hello Brian, > > > > I was hoping there would be a way to do this selectively within the > > confines of the K3 and not use something external.
