[ForSale-Swap] For Sale: 432MHz EME Antenna System

[Bob Kocisko]

Since moving to my new AZ QTH, I'm concentrating on putting up a 16' dish for 23cm EME & later will put up my old 2m EME antennas.  In 2002, I purchased a 432 EME system fm a ham in So Calif & never put it up.  The antennas & EL rotor were stored in my yard under tarps.  The person I purchased it fm bought it in 1991 & had it operational for 10 yrs.

The antenna system consists of 8 x K1FO 25 element yagis (16.5dB gain each yagi w/ 17' booms), heavy duty H-frame for stacking the yagis 2 wide x 4 high, Andrews LDF4-50A phasing lines (built & network analyzer matched by M^2), two 4-port M^2 pwr dividers & one 2-port M^2 pwr divider attached to a mast mounted box with a strong metal tube around it to keep it fm bending.  The metal mast mounted box is included but does NOT include any connectors, relays or LNA.  The H-frame risers are 17' 4" long & welded so can't be split apart to ship & a 3" diameter x 6' 6" long crossboom.  Also included is a very heavy duty M^2 MT-3000A elevation rotor & control box along w/ 90' rotor cable & connector.

Due to the weight of the EL rotor & length of the risers & antennas, I'm requesting pick-up only in Chino Valley, AZ (20 miles north of Prescott).  I can deliver it all to the Williams, AZ hamfest the weekend of July 18 & 19.  Alternately, it can be shipped if the buyer wants to pay for building shipping crates & freight charges.

Here's a breakdown of each item included, what the original owner paid in 1991 (based on receipts I have) & what I'm asking now if sold as a complete system which is my preference.  If purchased new today, prices would far exceed 1991 prices.  For example, the MT-3000A EL rotor + controller costs $3,500 & 8 of these yagis would cost $1,888 ($236 each) fm Directive Systems.
