Frequently Asked Questions
What frequency range does AH1G.225 cover?
AH1G.225 covers 433/470 868/915MHz. If your application needs a band outside this range, we can retune the matching network for your target frequency.
How is AH1G.225 packed and shipped?
For AH1G.225, unit weight is 1 g/pcs and standard packaging is PP bag. Bulk packing and custom labelling are available for volume orders.
What is the minimum order quantity and lead time?
Standard models ship in 7–15 working days after order confirmation; samples of in-stock models can ship within 3 days. MOQ depends on the model — contact us for the exact figure for your part number.
Can AntennaHome customize an antenna for my device?
Yes. We provide customized design including frequency tuning, connector and cable length, housing and mounting method. Send us your enclosure drawing, available ground plane size and target bands, and our RF engineers will propose a design.
What certifications and test reports are available?
Products are RoHS and REACH compliant. We operate an in-house 3D anechoic chamber and can provide VSWR, gain and radiation pattern test reports for the specific part number you order.

- Antenna Gain Explained: dBi vs dBd, and Why Higher Is Not Always Better — Antenna gain is directionality, not amplification. dBi = dBd + 2.15, and every 3 dB of extra gain halves the coverage angle — which is why a 3 dBi omni usually beats a 9 dBi omni on a device whose orientation you cannot
