Hello Alex,

Thank you, interesting to read!
I like to spend time alone in the nature. Siberia must be a very good place for that and for playing with laaarge antennas for LF/MF :-)

Hi Dimitris VK2COW,

Beverage was my favorite antenna for the reception at 136/500 kHz and 160-80-40m

I used beverage in all my LF DXpeditions - abt 2km long on Siberia 2 Rus LF DXpedition   (MO94TL80QU) and on Russian Far East 3 Rus LF DXpedition (PN63CI41RU) - abt 1.5km long to EU and abt 4km to ZL.

I used the enamel copper wire diameter of abt 0.5 mm to made the beverage. 

I gested the beverage directly on the the ground (BOG) - this was a temporary option. Weight of the enamelled copper wires with a diameter of 0.5 mm is abt 1.8 kg per 1 km length

I used the isolated wire (4 Cu + 3 Fe, 10.5kg per 1km ) for 1.2-2km long as BOG at the stationary place on Machta (KN97LN09IG) until 2010. LF/MF beverage can be placed under ground (10-30cm), I believe :-)

Some ideas abt optimal h for 160-40m is on DL2KQ  For example h opt for 240m beverage on 160m is 0.1m (80m - 0.65m and 40m - 1.9m)  240m is 1.5 Lambda on 160m (940m - 630m). BV 2km long is fine RX ant for 136kHz
