軸方向に移動し昇降する。ロック機構27をロックすると
内筒24は固定され、一方、ロックをゆるめると内筒24と
共に空中線22が昇降可能となる。なお、空中線22は無指
向性空中線であり、指向制御が不要なため、空中線制御
接栓等の取付構造を具備していない。Conventionally, this type of antenna lifting device has a structure as shown in FIG. That is, the antenna 22 is fixed to the lower end of the inner cylinder 24 via the antenna flange portion 23.
Is rotatably supported by bearings 21 and 26 of the flange portion 25, and is manually moved in the axial direction to move up and down. When the lock mechanism 27 is locked, the inner cylinder 24 is fixed, while when the lock is loosened, the antenna 22 can be moved up and down together with the inner cylinder 24. Since the antenna 22 is an omnidirectional antenna and does not require directivity control, it is not equipped with a mounting structure such as an antenna control connector.
上述した従来の空中線の昇降装置は、次のような欠点
を有していた。The above-described conventional antenna lifting device has the following drawbacks.
(1)手で持ち上下させる構造であるため、重量のある
大形空中線の場合は重く、また不用意に落下させる場合
もあり危険である。(1) Since it is a structure that it is held up and down by hand, a large antenna with a large weight is heavy and may be dropped accidentally, which is dangerous.
(2)軸受け部も外筒の中間部及び下部となっているた
め、大形の重量のある空中線の場合、下降時に飛行によ
る風圧により強度上不安が残る。(2) Since the bearings are also located in the middle and lower part of the outer cylinder, in the case of a large and heavy antenna, there is a concern about the strength due to the wind pressure during flight when descending.
(3)空中線の取付けに空中線導波管フランジのみに頼
っており、大形重量空中線の場合不適当である。(3) Only the antenna waveguide flange is used for mounting the antenna, and it is not suitable for a large weight antenna.
(4)空中線制御接栓を取付けできる構造ではない。(4) It is not a structure that can attach the antenna control connector.
