I live in a apartment on the first floor so you can imagine my antenna problems....
My balcony however is 10m. long ,so i mounted a horizontal endfed antenna downcaled for 20-10m on the wooden windowframe . Because of the capacity of the wood and the paint overall length was reduced to aprox. 9m.. but provided a near 1:1 swr on 20 and 10m.
First contact on 10m. using 10 Watts SSB was with 5B4AHL (5-9) on cyprus folowed by 9K2QA (5-9) in Kuwait and 4S7VG (5-8) in SRI Lanka despite of a huge pile-up. This antenna is going to stay HI.
More info about this antenna on my site:http://pa-11019.blogspot.nl/ (http://pa-11019.blogspot.nl/)
Have fun

Hello John,
I love it and keep it for future reference.
I want to try especially the EFHW = End fed Half Wave antenna, but have to wait to warmer temperature
here :--)))
All the very best and hope to meet you on the air too.
