Testing my new mast, Cobwebb vs end fed and possibly the 10m yagi
Tomorrow I will be testing my new home made portable aluminium mast. I have constructed it using various widths of aluminium loosely fitting pipes and clamps. Theoretically it should be able to reach 13m (42ft). I will update my Projects page with more info and pictures later.
I hope to be able to set it up attached to my car without further (guying) support and reach at least 10m (33ft). It will be interesting to see if it can hold my 10m 4-el yagi (6kg) at that height.
If it works out well enough I will raise my Cobwebb 5-band antenna (only 2kg) and compare it head-to-head with my half wave end fed wire antenna to see which of the two is the better /P DX antenna. I just hope conditions on the higher bands are favourable tomorrow.
A dipole's effectiveness depends a lot on its height above ground. With the Cobwebb's lowest band being 20m, a mast that goes up to 10m does not make it a DX killer on the lower of the five bands. However, I think it is fair to say that 10m is very reasonable height for a /P operation.
