[TowerTalk] HF6V - any help for 80

[py4ro@ig.com.br]

Dear Kelly, 

I have used the HF2V from 1995 to 1997 and when it was elevated 10 ft with a 
few radials it was a killer on 40m and a good antenna on 80m. In 1997 I 
decided to replaced it with dipoles for both bands... I lost tx but the rx 
improved a lot. 

The HF2V is similar to your HF6V since it is base loaded for 80, isn´t it? 
But see that a vertical antenna has a low radiation angle and for short 
distances it is not a good antenna (even for transmission)... That is the 
reason many hams prefer dipoles for in-house contests. W0AIH is close to 
you?? About 1000 km?? If that is the case it is normal!!! I used to hear São 
Paulo from Rio with weak signals using the HF2V... a low dipole was a much 
better performer for that job. 

Well, unless you have a regular receiveing antenna, I DO prefer dipoles even 
for dx contacts. 

There is an article (QST or Antenna Compendium) that an american ham 
describes an elevated HF6V with shortned radials. If I am not wrong he 
achieved the DXCC on 40 and 80 with this setup. 

Good luck!
