[Milsurplus] VLF & ELF Antennas

[David Olean]

Hi Mike,

I have an MN-26C Bendix receiver running and have listened for NDBs as 
well as European long wave broadcasts. I just plug it into a beverage 
antenna and hear literally hundreds of NDBs.  There are a few power 
houses, one of them being a 1 KW station in the Cayman Islands. It is 
loud at night.  I hear a 25 watt station from Nova Scotia a few hundred 
miles away during the day, so you can get a feel for the positive 
effects of salt water!! A 1 KW NDB in Montreal is closer but is weak 
during the day.

The problem with beverages is that they take up waaay too much room!   
Many people have luck with ferrite rod antennas. a group of long ferrite 
rods bundled with many turns of wire wrapped around it can be very 
effective and is small and rotatable. I never made one, but those who 
have swear by them for LF reception.

I have a good friend in Fredericksburg, actually Chancellorsville. I 
visit there every spring.

I also use an old Bendix RA-10 RX on 150-400 kHz. It works great too.
