I read about the rain pipe antenna many times, but never thought it would work for me in an apartment. Finally gave it a try some weeks ago and have not regretted it. Rain pipe has one approx 33' (10m) horizontal and two 24' (8m) vertical elements. Connection is on the balcony via a thin insulated wire. Counterpoise is laying on the balcony, approx. 24', I am still playing with the optimal length. SWR 1.5:1 currently.
This gets me on the AR Razorback Net on 3987.5 every time I am able to set up my transceiver.
Reception reports throughout AR are variable, but sufficient to get me out.
