La RadioMaster DBR4 Dual-Band Xross Gemini è una ricevente ExpressLRS che lavora contemporaneamente sulle bande 2.4 GHz e 900 MHz grazie alla tecnologia Gemini Xrossband. Con due chip Semtech LR1121 e quattro antenne separate offre un collegamento radio estremamente robusto, ideale per long range, ala fissa e droni FPV dove la sicurezza del link è prioritaria.
RadioMaster DBR4: doppia banda in contemporanea
In modalità Gemini Xrossband la DBR4 riceve lo stesso segnale su 2.4 GHz e 900 MHz nello stesso momento: se una banda è disturbata o coperta da ostacoli, l'altra mantiene il controllo. Puoi usarla anche in Gemini su singola banda. Per sfruttare la doppia banda serve un modulo o una radio Gemini Xrossband, come il RadioMaster Nomad.
Il formato 20x20 mm con gommini antivibrazione la rende semplice da montare nello stack, e il sistema di raffreddamento dedicato tiene a bada le temperature.

Under the 24-month Legal Guarantee, Drone24Hours is responsible to the consumer for any defects in conformity that cannot be detected at the time of purchase.
The lack of conformity exists when the product is not suitable for the use for which it is normally intended, does not conform to the description or does not possess the qualities promised by the seller, does not offer the qualities and performances usual for a good of the same type, is not suitable for the particular use desired by the consumer if brought to the attention of the seller at the time of purchase and accepted by the seller (art. 129 of the Consumer Code).
Any lack of conformity which becomes apparent within 24 months of the date of purchase of the goods must be reported within 2 months of the date of discovery of the defect.
Unless proven otherwise, it is presumed that any lack of conformity that becomes apparent within 6 months of delivery of the goods already existed on that date. In the event of a lack of conformity, the consumer has the right to have the conformity of the goods restored, free of charge, by repair or replacement (art. 130 of the Consumer Code).
The consumer may ask, at his choice, the seller to repair the goods or replace them, free of charge in both cases, unless the requested remedy is objectively impossible or excessively expensive compared to the other. Repairs or replacements must be carried out within a reasonable time from the request of the Consumer; the average time for returning the product to the Consumer is 20 days.
If Drone24hours is unable to return the repaired product within the maximum period of 60 days, the consumer may request one of the alternative remedies (replacement, termination of the contract, price reduction).
Drone24Hours will send the product for any repairs to the Technical Assistance Center authorized by the Manufacturer.
What happens if the Service Center does not find the lack of conformity?
If the lack of conformity is not found, Drone24Hours will communicate the estimate to the Customer, who can decide whether or not to carry out the repair at his own expense. In this case, any transport costs and diagnosis of the defect requested by the Assistance Center will be borne by the Customer.
