good standard but there is better versions out there look carefully through the link find correct frequency ie 433mhz etc look for better gain, it's like my remote controlled bait boat had standard antenna but with improvement of them it goes further than it should. same with rca helicopter, or petrol rca car, everything can be slightly improved in someway over standard factory release products, that's why I'm a tinkerer and always look to improve or modify to suit my needs, I'm finally run through projects and in two weeks I'm free, but want take long before I start looking for ideas or helping do projects, I have to keep brain going I've worked on many things with Alex for our industry then fishing one offs or testing even down to new baits, I've been working as a part time gunsmith over last couple of years in tuning an experiments even down to modify valve sets for pcp, but it's time to return some old thoughts back to our industry for a while , it goes full circle as I have contacts in each field but can't do them all at once a year or so in each would be ideal but doesn't always workout that way, plus my family require me then so does local farmers for pest control, I never seem to stop, but I'm gonna slow down spent a set time in each area at a time, now it's back to wfp
