ANTHF - Hy-Gain 14 VRQ Antenna: I realize this is a bit of a crapshoot but I figured why not. I am hopeful to source a Hy-Gain 14 AVQ vertical antenna. I read and hear nothing but good things about them. I have an older ham who has made an 80 meter coil for one available to me very affordably. I figured if I can find an antenna available for a decent price as well it was a sign. Here's me shooting a sho at it.; Listing #1766955 - Submitted on 05/03/26 by Callsign KC1ZEW, Modified on 05/05/26 - IP: 216.252.222.13; Click to Contact -- Send this Ad to a Friend

TEST - BIRD 2500 WATT DUMMY LOAD: I have available for sale a BIRD 2500 watt dummy loaded, model 8892-300. This load came to me with a 1-5/8 inch flange interface sticking out from the load. I have added an adapter plate which allows me to use any BIRD Quick Change connector. Currently there is an LC female connector on it, but I can change that to whatever series connector you would like - - let me know your connector preference. This load also has the optional temperature sensor switch (located on the front above the input coax connector.)
-
See the attached picture.
-
Because of this load's RF input connector protruding out the front, there would be an increased possible damage if this were shipped - - so I WILL NOT SHIP THIS LOAD.
I can deliver this in person at any local hamfest or at the DAYTON HAMVENTION.
-
The price is $1250.; Listing #1765443 - Submitted on 04/19/26 by Callsign K3DUA, Modified on 05/05/26 - IP: pool-173-69-135-23.bltmmd.fios.verizon.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
