Appointment:
It is designed to measure the energy flux density of an electromagnetic field in conjunction with measuring receivers, and with generators – to excite an electromagnetic field with a given energy flux density in the operating frequency range. The antenna is used to measure the parameters of antenna devices and the parameters of electromagnetic compatibility of electronic means. The antenna can be used for work in laboratory and factory conditions. The principle of operation of a logoperiodic antenna is based on converting the energy flux density of the electromagnetic field into the corresponding high-frequency power in the path, or converting the RF signal supplied from a generator or power amplifier into electromagnetic field energy. The antenna has linear polarization.Description:
- The antenna is a common-mode antenna array of two logoperiodic antennas of linear polarization. Structurally, the web of each antenna consists of a collective line in the form of two traverses located one above the other, simultaneously performing the role of a supporting structure. The shoulders of vibrators of circular cross–section are alternately attached to these traverses as follows: the left shoulder of one of the vibrators is attached to the upper traverse of the collecting line, and the right shoulder of the same vibrator is attached to the lower traverse. The length of the vibrators and the distance between them vary exponentially. The excitation of the two-wire line is carried out by a 1/2" coaxial cable laid in the center, along the traverse of the collecting antenna line.
- At the place of the electrical connection of the two antennas, the energy flow of the electromagnetic field is summed, taking into account the phases received (radiated) RF signals. Summing the signals of two identical logoperiodic antennas, taking into account phasing and changes in the distances between the traverses, allows you to narrow the directional pattern of the antenna array with respect to a single antenna of the logoperiodic structure, which allows you to increase the system gain by 2....2.5 dB.
- The antenna has a coaxial microwave input with a 50 ohm wave resistance of the 7-16" socket type located on the mounting node.
- The antenna design in the frequency range provides a small voltage standing wave coefficient (VSWR) and a monotonous frequency dependence of the gain.
- In order to reduce the overall dimensions of the antenna, the rear vibrators have a special shape. The antenna design provides for the possibility of its attachment to a specialized mounting device in agreement with the Customer.
- Verification is included in the cost of SI.

Payment by bank card online
You can pay for the goods with bank cards "Visa", "Master Card", "Mir", "JCB". Payment by bank card is made without commission.- your bank card number;
- expiration date of your bank card;
- CVV code for Visa / CVC code for Master Card: the last 3 digits on the signature strip on the back of the card;
- confirm the card transaction, for example, with a one-time password from an SMS.
Payment according to the invoice
On the checkout page, select the “Invoice payment” option, and after placing the order, the system will automatically generate and send you an invoice for payment to the specified email address.Payment with bonuses
The buyer can pay part of the order cost (up to 20%) with Enex bonuses. The procedure and conditions for calculating and debiting bonuses are specified in section 7 Rules of sale and delivery.The seller's indication on the marketplace
Various suppliers of tools and equipment trade on the Enex marketplace. These can be both manufacturers and trading companies. In this case, the Marketplace acts as an agent (Chapter 52 of the Civil Code of the Russian Federation). Enex itself can also act as a seller for some products. Learn more about ordering from different suppliers.Return of goods
Is it possible to return the purchased product?
If you are not satisfied with the product purchased on the Enex platform, you can return it or exchange it under the conditions specified below. Since buyers conclude direct purchase and sale transactions with manufacturers on the Enex platform, the return of goods is carried out directly to manufacturers.
Return of goods of proper quality
For individuals
The buyer-an individual has the right to refuse the ordered goods at any time before receiving it, as well as after receiving the goods - within 7 days, not counting the day of purchase. The return of the goods is possible if its presentation and consumer properties are preserved, as well as a document confirming the fact and conditions of purchase of the goods.
The buyer does not have the right to refuse a product of proper quality having individually defined properties if the specified product can be used exclusively by the buyer acquiring it.
In case of refusal of the goods of proper quality, the cost of services for the organization of delivery to the buyer is not refunded. Transportation costs for the return of goods of proper quality are borne by the buyer. The method of returning the goods is determined by the buyer.
For legal entities
The return (exchange) of goods of proper quality by the buyer, who is a legal entity (individual entrepreneur), is not allowed, unless otherwise provided by the agreement with the supplier.
Return of goods of inadequate quality
For individuals
The buyer, who is an individual, in cases provided for by law, may return the goods of inadequate quality during the warranty period for the goods and demand a refund of the amount of money paid for the goods. The goods of inadequate quality, in agreement with the buyer, can be replaced with a similar product of proper quality.
For legal entities
The buyer, who is a legal entity (individual entrepreneur), in the event of the transfer of Goods of inadequate quality to him, has the right to make claims provided for in Article 475 of the Civil Code of the Russian Federation.
Distribution of responsibility
In case of return/replacement of low-quality goods, the cost of delivery of the goods is paid by the supplier. The supplier reserves the right to accept the goods of inadequate quality from the buyer and, if necessary, to check the quality of the goods. If, as a result of the examination of the goods, it is established that its shortcomings arose due to circumstances for which the supplier is not responsible, the buyer is obliged to reimburse the supplier for the costs of conducting the examination, as well as the costs associated with its storage and transportation of the goods.
If any defect is found in the product, the manufacturer and (or) the marketplace has the right to require the buyer to provide a photo of the product, the claimed defect, packaging, labeling (nameplate) of the manufacturer.
If the buyer, who is a legal entity (individual entrepreneur), refuses the goods of inadequate quality, such buyer is obliged to return such goods to the supplier. The buyer - an individual can also return the goods to the address of the supplier or Marketplace.
