New Antenna mast at VU2SWX

June 13th, 2008

A new antenna mast was installed at VU2SWX  ham radio station. The Mast is approximately at a height of 18 meters from ground level. The following photographs show the installation.

Antanna base

The base of the mast.  It consists of 1.5m  2 inch GI pipe  fixed on  parapet. It is also  bolted to the side wall. The  bottom side is fixed on a concrete block.

The top  end of the mast. It has a pulley attached to a piece of pipe as shown.  Another piece of pipe was welded above the triangular piece to fix a VHF vertical dipole.

The  hooks on the mast for guy wire. The actual mast is fabricated from 4 pieces of GI pipes. Each piece can be detached if needed.

Antenna  mast installation

Starting the installation. The installation was some what tricky. There is a power line near my house. So the  guy wire were attached to hooks so as to avoid  the possibility of any  electric shock.

After the installation.

There are 4 guy wires. The guy wires are isolated  from ground via a piece  of PVC pipe  The guy wires were tied to  hooks on the terrace. There is a nylon rope on the pulley so that I can easily  mount an inverted V for HF bands.  I am yet to fix the antenna. Hopefully, I will be QRV by the  end of my vacation.

Update. 28th April 2009

My friend  OM VU3RDD wanted to look at  VU2SWX  mast for ideas  and a game plan for  a mast he is planning. So I have set up a picasa webalbum here.

    Wow !!!!
    I always wished we also did stuff like the westerners, we also documented it like them. Now I am seeing just that.

    Nice work Sunil ! Looks like you had a lot of Ham/SWL help !

    I would have preferred a wooden mast (I had one that I built from pieces of long scrapwood salvaged from sawmills near my QTH at Trivandrum – it is easy to make one and will last for a very long time). I hope that the antenna is away from nearby powerlines. 73 de salim vu2lid / n8li

    Nice job – both the antenna and documentation.

    Yes, as VU2LID said, I also would have preferred a woodern installation though my antenna (excluding the top portion of the mast) was also a GI pipe. One good solution for a mast is a good bamboo pole.

    The pictures explain a lot but you could write more on the steps that were undertaken to accomplish the task. Block diagrams and rough sketches could complement the write-up.
