The construction of an antenna mast can be simple and safe as long as it is done correctly. Radio amateurs when broadcasting from intermediate stations are faced with the task of how to get the antenna to the required height. The summary of the following videos will show several options on how to do it and what not to do.

Tip: how to make a quality mast?
Peter's video OK1 FIG reveals how a mast can be assembled from available materials. It is also possible to notice the unconventional way of mounting the antenna, which is faster than the usually used cross mount.
Construction of a 9m mast by pushing it up
Better not like this. Lifting the mast is a matter of lever physics. The higher the mast, the more difficult it is.
Mast launch with four DK7ZB yagi antennas UV1S
Alas, this doesn't look doubly safe either. Although in the end the mast was lowered.
9A1CRS VHF portable
A stronger mast and enough hands…
OK1HWU took advantage of building a mast over a needle
Not everything can be seen on the video, but several details can be observed.
F8KCF/p use a telescopic mast
Paradoxically, however, they did not use this option - raising the antennas in the axis. But you can see a good interplay during the construction and a good distribution of anchor ropes after 90 degrees.
PI4MAX lifting the mast through the needle with winch
The auxiliary "needle" looks subtle, but using the winch on the car to raise the mast is a significant help.
F6ETI/p raising the mast by the car
A smaller mast can be lifted by the car relatively easily. The garden on the car is used first as a bearing point and later as a support point for the erected mast.
OE5LHM/p – mast construction in winter
Harald used a tube in the heel instead of the usual joint. This probably also contributes to stability and is an option if it is necessary to build a mast on a base in which it is not possible to install the joint.
IK4WKU/6 destruction of antennas
Broadcasting from high altitudes also brings risks. Here it is doubly true that the antennas must be built safely!
A square of 9-element IQ4AX antennas
Lifting against a fixed support looks easy, doesn't it?
IQ3RO with a lot of aids on the condition of the antennas
The use of a structure in the base of the antenna enables good lifting of even larger antennas.
IQ4AX mast lifting against support with hoist
Excellent method! The hoist is a system of several pulleys, which reduces the force required to pull out the antennas.
DL7AFB – precise unmooring and lifting of a 15m mast
If it is thought out and done well, even such a mast with antennas can be raised.
LZ4BF – raising two 12-element DK7ZB yagis to 144MHz
Can two long VHF antennas be lifted by one person? LZ4BF also used the hoist and the construction of the antenna through the needle. And suddenly it looks easy, doesn't it?
