 移動運用向き 小型アンテナ
★シルバー色 片持ちダブルリフレクター 高剛性 紫外線劣化するプラステイック一切不使用
  全金属製 1200MHz用 8エレメント ループ八木アンテナ★


(1280~1300MHz)VSWR 1.2以下
 各エレメントには幅10㎜で厚さ2㎜のシルバー色アルミニウム平板を使用。
 アルミニウム製エレメントは軽い反面 エレメントを円形にしても、つなぎ目を溶接しなければ
 高周波における電気的性質が不安定になり最悪の場合はエレメントとしての機能が失われてしまいます。
 このアンテナは各エレメントをブームに2本のステンレス皿ネジでしっかり締め付けし さらに強力な接着剤で
 留めました。
 使用中に緩むこと、向きが変わることはありません。
 高周波的にも経年劣化しません。

 第一リフレクター後部にさらに第2のリフレクターを追加しました。
 2段構えのリフレクターは期待した以上の効果がありました。
 リフレクター追加によりシングルリフレクターより10dbほどFB比が向上しました。
 ラジエーターは銅製・ディレクターはシルバー色処理した10㎜幅 2㎜厚のアルミニウム平板使用。

 一般に行われている ブームを貫通させ ラジエーター上部から給電する方法も採用してきましたが
 やはり完全な給電はエレメント下部からの方法が安定な給電方法です。
 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1.5㎜の15㎜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補助部品を作りました。
 反対側には角パイプと相性が良いマスト取り付け部分をアルミニウム材で作りました。
 Uボルト1本により25~30㎜φのマストにしっかり取り付けできます。

 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
 塗装は素人ですので色むら等ありますがご了承ください。

 ブーム長は約33㎝
 アンテナ利得:推定利得 約11dbd(1/2波長ダイポール比) 約12dbi
 アンテナサイズ:全長約33㎝ 全幅 約10㎝×約12㎝(支持部品を除く)
 アンテナ重量 垂直偏波用取り付け部品とも約350g

 回転半径 約30㎝
 NJコネクター
 給電インピーダンス 50オーム
 耐入力:100W 同軸5DSFケーブル他5D系において

International Shipping Methods
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.my 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.
