This monobloc base is made from thick highly resistant aluminium (see description below).
4 x 6 mm thick ribbed braces are supplied and also allow the clamping of a tube of 50 - 45 - 40 - 35 or 30mm diameter.
Large 3mm thick nylon washers are available as an option for tubes of intermediate diameters. They are equally useful for clamping a mast or cane in glass fibre and also avoid abrasion on the aluminium when tilting.
Spindles of 10mm diameter can be made with threaded bar or a large bolt (stainless is advisable). If, however, you do not have what is needed to make it, there is that option available in this catalogue.
This monobloc base can be mounted horizontally (ground, terrace...), vertically (frontage, post...) or inclined (beam, sloping roof...)

DX AVENUE Hints and Tips
Experience has shown that the erection of a vertical antenna is very much easier when it can be tilted whilst being held by its base. This theory is even more true when it concerns vertical antennas (or tubular masts) of large size as, for example, a quarter wave for 7Mhz (10.5 m) or 3.5Mhz (21m).
For adjustment and maintenance, it is enough to lightly loosen the spindle at the base and release a spread of the guys in order to be able to tilt the antenna (or mast) gently.
