★未使用新品 高剛性 紫外線劣化するプラステイック一切不使用 全天候 全金属製 430MHz用 17エレメントパラレル ループ八木アンテナ ★

周波数帯域の広い430MHz帯バンドに対応
しっかりした作りですので全重量は2本のアンテナと支持部品との合計で約10Kgあります。
430~440MHzはVSWR 1.5以下 432~437MHzはVSWR 1.2以下
各エレメントには幅広(10mm)で厚み2㎜のアルミナ処理の硬質化したアルミニュウム板使用。
繋ぎ部分は雨等による電気的劣化を起こさないよう十分な処理済み。 高周波的にも経年劣化しません。

ラジエーター加工は20㎜幅2㎜厚のアルミナ加工アルミニュウム製 オープンループに仕上げました。

NJコネクター
給電位置はエレメントの下部からブーム取り付け位置
機械的強度も高く高周波的にも安定した給電ができます。


一般には ブームには価格が安いため丸型アルミニウムパイプを使用することが多いようですが
このアンテナには高価な厚みが2㎜の20㎜角アルミニウムパイプを使用しました。
エレメントをしっかり取り付けるには角パイプのほうが優れています。
丸パイプより曲げにもとても強いのでしっかりしたアンテナに仕上がりました。

垂直偏波が一般的なためにアンテナブーム後部にアルミニウム材で頑固な2段構えの補助部品を作りました。
2本づつのUボルトにより30~50㎜φのマストにしっかり取り付けできます。
ブーム長は3.1m


当方 貴金属装身具製造を生業としておりますので可能な範囲で丁寧に製作しておりますが
多少ですが 擦りキズ、塗装むらがあります。ご理解・ご了承ださい!
アンテナ利得:推定利得 約18dbd(1/2波長ダイポール比) 約20dbi
アンテナサイズ:全長3.1m 全幅 約1.6m×約0.33m(支持部品を除く)

回転半径 約2m
通常のNJコネクター仕様
給電インピーダンス 50オーム
耐入力:300W 同軸5DSFケーブル他5D系において
取付マストは、30~50㎜φで垂直偏波用

VSWR
周波数430MHz~440MHzにてVSWR 1.5以下

International Shipping Methods
Singapore Package Import: Customs and Tax Policies
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao-holdings.com and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
