Radio Kit Lite - Rambler G4 GMRS Band Mobile Radio with Stealth Antenna
The Rambler G4 is built for enclosed cab vehicles and designed to thrive in harsh off-road conditions. It features a user-friendly LED display, external speaker port, and high-clarity signal output for trail coordination and emergency response—ensuring your crew stays connected in terrain where cell signals disappear.
GMRS delivers stronger transmission power, cleaner audio, and repeater capability. CB radio is static-prone, range-limited, and increasingly obsolete for serious off-road and overland use.
Stay Connected, No Matter Where You Roam
The Rambler G4 is built to keep your crew talking when the grid goes quiet. Reliable, powerful, and field-proven—it’s the communications upgrade your rig deserves.
"A prudent person foresees danger ahead and takes precautions. The simpleton goes blindly on and suffers the consequences. - Proverbs 27:12"

Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
Is the Rambler G4 repeater-compatible?
Yes. It supports split-tone configuration for repeater networks.
Does it work with my existing GMRS radios?
Yes. Fully compatible with all GMRS radios and FRS on shared channels.
Is it waterproof?
No. The G4 is optimized for enclosed cab use. For waterproof options, see the Rambler G1.
Can I use this with an intercom or headset?
Yes. The external speaker port supports 5-pin accessories via an optional jumper cable.
Do I need a license to use this?
Yes. A GMRS license is required but easy to obtain and covers your entire household.
How long does shipping take?
Most orders process within 1–3 business days from our warehouse. From there: 5–7 business days economy, 2–3 business days expedited, or overnight if you need it fast. Free economy shipping on orders over $150 (contiguous US). Alaska, Hawaii, and Pro Eagle / freight items are quoted at checkout. You’ll get a tracking number and link the moment your order ships.
What’s your return policy?
30 days from the day your order arrives. Gear has to come back unused, with all original tags, stickers, and packaging intact. For standard items we’ll send a prepaid return label and deduct return shipping from your refund. Oversized or freight returns are on you, unless the item showed up damaged, defective, or wrong — in which case we cover it.
Refunds hit your original payment method within 10 business days of approval.
What can’t I return?
Final-sale items, gift cards, food and drink products, personal-care items, anything customized or engraved, briefs (hygiene), and hazardous materials. If you’re not sure whether something qualifies, email us before you order — we’ll tell you straight.
Do you ship outside the contiguous US?
Yes. Alaska, Hawaii, and US territories ship on freight-quoted rates calculated after checkout. International orders are available worldwide at variable rates; duties and import fees are the customer’s responsibility. EU customers get a 14-day cancellation window per EU consumer law, on top of our standard return policy.
My package arrived damaged — what now?
Email info@stayreadyoutdoors.com within 7 days of delivery with your order number and clear photos of the damage (product + packaging). We’ll replace, refund, or ship a return label on us — no back-and-forth. Damaged, defective, or wrong-item claims never cost you shipping.
Can I talk to a human before buying?
Yes. Email info@stayreadyoutdoors.com — we answer every message ourselves, usually within a few hours during business days. We carry this gear, we use this gear, and we’d rather talk you out of a kit that doesn’t fit your mission than sell you the wrong one.
Do you offer a military/first-responder discount?
Yes. Active-duty and veteran military, police, fire, EMS, and medical first responders get 15% off every order. Verify through GovX at checkout — one-time, secure, and reusable across thousands of brands. Discount applies automatically once you’re verified.
