An antenna (10) includes a boom (12) which through insulator blocks (15) carries a plurality of elements (13) consisting of element halve s (13A, 13B) which extend in opposite directions from the boom (12). The insulator block (15) includes compartments (18) to receive the element halve s {13A, 13B) and a pedestal (38) formed below each compartment (18) provides strength to that area of the block (15). The block (15) has opposed sidewall s (22) with surfaces (24) to receive the boom (12). The bands (33) of a clamp hold the boom {12) and are received in the space between the pedestals (29) and the sidewalls (22). A crass-shaped member (27) is also located between the sidewalls (22) to strengthen the block (15) while at the same time reducing the weight thereof.
