As I mentioned, they can use slightly different Lithium technologies.

AA 1.5v Lithium rechargeables exist but are not particularly cheap, eg. one example, see
https://www.batterystation.co.uk/xtar-1-5v-aa-2200mah-lithium-rechargeable-batteries-4-pack/
There are other (major) sellers who I don't like, so not quoting !!

For your 3v CR2's here's one example which comes with the special charger
https://www.ebay.co.uk/itm/364242658282 but beware there are some other sellers (major again) who can't seem to distinguish between a 3v and a 3.7v, the latter being slightly longer, and/or non-rechargeables !!!

As for the LP. I'm not sure what you mean by 13 "whole" elements. Each rod is separate on a LP. The lengths of the rods determines the range of frequencies it will receive and the number will determine the gain as well. You can zoom in on the links I gave. I think Blake have been in the business long enough to know what they re doing!!

Here's some additional reading for you -

Chris SE,
Thank you for so much info to study.
I still don't know, though, for example, what makes one lithium 1.5v battery rechargeable and another 1.5v lithium battery not.
I should have said my log is 16 whole elements, [I am speaking as of a yagi.] That is 32 of your little ones.

Chris SE,
I have been in touch with Blake. I believed logs were meant to be good at rejecting signals from the rear. They say not and that their DMX range are better. Since their largest dmx is pretty much the same as what I have made myself, I doubt I would see any improvement.

nick horrex:

I'm totally surprised that someone from Blake has said that logs aren't good at rejecting signals from the rear, they are, and very low/no sidelobes, they are also good at impulse noise rejection, good cross-polar rejection and they also have a flatter response and considerably less wind resistance!

Perhaps you were talking to someone from Sales, just wanting to flog you a more expensive aerial, they're at least 10 & 20 more depending on the number of elements!
I suggest you get back in touch, ask for technical support and ask them if they can email you the polar diagrams for the DMX10K-F and the BLA-LP56K

In the meantime have a look at this from ATV Aerials and TV
Their XB10 range is almost identical to Blake's DMX10s
https://www.aerialsandtv.….jpg
Compare to this
Aerial polar response diagrams A.T.V. Poles, Brackets, Clamps & Aerials
You will note the absence of sidelobes and low rear rejection for the LP in this second graph top LH plot.

You will find similar information from multiple sources (not just the sellers) if you bother to do the research. Frankly, you have no idea exactly what your homebrew aerial performs like unless you have had it professionally tested. It could have a very peaky response, have particular problems with 602MHz - C37 etc.etc.
You have been bleating on about the C37 problem for months and months, so long I've lost count. Yet you seem unwilling to take the simplest of steps to eliminate possibilities, the free Filter to eliminate Mobile signal interference. The problem may go away and your home brew could continue to give years of service. If it doesn't then my next choice would be a decent well made LP as already suggested, but you try what you like.

Chris SE, thanks.
I was communicating online, and he sent diagrams. It started with your advised log but ended up with the highest gain which from the 'x' type.
I have made extensive tests with my homebrew, just for my own interest, testing at each tiny change. I have altered spacings, length of elements, width and height of reflector and it is one of the few that gets 37. lengthening of elements brings better signal on 29, but if I do too much it loses on 47. I am particularly proud of the dipole which I call batwing, substantially larger than most.

Any more thoughts on 1.5v lithium batteries?

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
