Some Base Station Solutions

Buy a SWR Meter or Borrow one - you will not get succeed if you don't

Solution #1 Magnet Base

Any antenna can be put onto a magnet mount and placed onto a metal roof or a metal railing off a balcony or even upside down on the guttering of a house.
But you will need to test the antenna as the antenna just may need to be tuned or lengthened

There are ways to to this that if not done right will give you a headache.

mag
Mag12C
This can be supplied with whatever length of cable required

 

dx170fw


DX172SW Is a good choice as it is very broadband and so may not need tuning

 

Ground planes react differently with the type of antenna - the shorter the antenna the smaller the ground plane required



For advice do NOT e-mail but do not hesitate to call Peter 10am to 5pm Mon to Fri on 0246-556677

 

Solution #2 Dipole

Any two 27MHz antennas can be mounted as a dipole as long as the antennas are the same length and frequency ie: Identicle
dipole
DM12C
Can be supplied with whatever length of cable required

rdrm

The configuration can be almost any two 27MHz antennas however there are limits and rules to follow


The longer the antennas the better and the more broadband the antenna will be

It is best if both antennas are identicle but with the bottom antenna slightly longer in order to tune

If both antennas are pre tuned then it should work ok but it should be tested and fine tuned

It can be either horizontal or vertical

It is important that the antenna is not earthed, The base section should be insulated from the mast and not run up along side the mast, this is important.

One way of mounting this antenna is to insert the bottom antenna inside conduit and mount the conduit to a mast

the bottom antenna has to be higher than the mast

 

This dipole is by FAR superior than any ground independent 27MHz antenna in many ways

 

Only DO NOT mount either top or the bottom of the antenna so that it running along next to any other metal object

it must be at least 400mm free of any othe antenna ( eg will not work on a mirror mount of a truck)


For advice please do NOT e-mail but do not hesitate to call
