[TowerTalk] Hygain MK160A

[Joe Subich, K4IK]

Gregg, 

It "works" as a way of getting the Hy-Tower on 160 meters. 

1) the resulting antenna is an inverted L of about 24' height. 

2) The feed impedance is quite low (SWR will be relatively 
   high unless you have a very lossy ground system).  

3) The efficiency of a 24' tall inverted L will be quite low

4) The inverted L will have a substantial amount of high angle 
   horizontally polarized response (as much or more than the 
   low angle, vertically polarized response ... particularly 
   if you have poor ground and/or a sparse radial system).   

The MK-160A is very expensive ($120 list) for what it is - 
an ordinary 40 meter trap.  The MK-160A is one half of the 
DP-2BDQ trap dipole which lists for $140! 

You can save a lot (ca. $65) by buying a PAIR or Reyco KW40 
traps from AES ($42.99 @ www.aesham.com) or Radioware/Radiobooks 
($41.79 @ www.radiobooks.com) and essentially making your own 
MK-160A. 

73,
