Title: A solution for OPs stuck in some condo? DCTL Antenna!
Post by: hs0zfe on September 12, 2010, 10:54:15 AM
DCTL (Distributed Capacity Twisted Loop) by WA6QBU.

Anyone built one? They are small and should be working well, also for those travelling.

Here are building instructions!

Seriously, the makers of the C3 antenna might want to consider making this antenna as there are countless ops in need of a balcony antenna!

Title: Found a commercial "condo antenna"

I ordered it and will report how it works. A new company is now making them and the price including shipping for the EF-20 is $ 67.

Getting on the air in some hotel room or condo is very important to the hundreds of visitors to our shores, too. Hence my hope that the makers of the C3 will also make a similar antenna locally  ;)

Here are some reviews of this type of antenna:

Sorry, no link - but I read a scientific paper on how lossy the average short compromise vertical is and remember that 100 W RF was heating up metal and 1 or 2 W being effectively radiated.

So you think your 10 W FM on 2 meters get radiated as 10 W RF power?  :D  ;D
